TH15 Upgrade Priority Guide 2026: What to Build First at Town Hall 15

Q: What should I upgrade first at TH15?

Build the Monolith and both Spell Towers on Day 1. Simultaneously upgrade the Laboratory, an Army Camp for housing space, and Barracks to unlock Root Rider. These five Day 1 assignments set up the first month of TH15 efficiently.

Q: Should I unlock Dragon Duke at TH15?

Yes. Upgrading Hero Hall to Level 9 to unlock Dragon Duke is a meaningful 2026 priority at TH15. He's the only Town Hall where you can field all six heroes. At TH15, his Royal Rampage passive is highly effective because defenses don't hit hard enough to counter him quickly. Get him to Level 5 and max Fire Heart equipment as soon as possible.

Q: What's the best Spell Tower loadout for defense at TH15?

Poison Spell is the most broadly effective defensive load. It shreds kill squads — hero groups and Queen Charge combinations — which are the primary threat against most TH15 war bases. Rage Spell Tower is a strong alternative if your Clan Castle troops are positioned near the Tower.

Q: How important are walls at TH15?

Less important than at lower Town Halls. Root Rider passes through walls, and air strategies bypass them entirely. Upgrade walls with overflow Gold after your defenses and heroes are on track — never let them compete with active upgrade timers.

Q: Which pet should I unlock first at TH15?

Frosty is the highest-priority pet at TH15. Paired with the Barbarian King or Archer Queen, his freeze effect and Frostmite spawns make the hero significantly harder to stop. Phoenix is the second priority — the revival effect during hero ability use is one of the most attack-deciding mechanics in war at this level.

Q: What new troops does TH15 unlock?

TH15 unlocks Root Rider, Dragon Rider, and Electro Titan as new troops, plus Recall Spell and Revive Spell. Root Rider is the most immediately impactful — it passes through walls and is the cornerstone of ground smash strategies at TH15.

Town Hall 15 sits at a unique position in the CoC progression ladder. You’ve unlocked two completely new defensive buildings — Spell Tower and Monolith — that don’t exist at any lower level, and you now have access to the most powerful hero roster the game has ever offered, including the newly released Dragon Duke. The decisions you make in the first two weeks at TH15 determine how quickly your base becomes genuinely threatening in war and CWL.

This guide follows the 2026 meta, accounting for the Dragon Duke’s release in March 2026 and the current attack landscape dominated by Root Riders and Dragon Rider air strategies.

What TH15 Unlocks: New Buildings, Troops & Heroes

Before setting upgrade priorities, it helps to know exactly what’s available at TH15 that wasn’t before. Several of these unlocks are genuinely high-impact and should shape your build order from Day 1.

Exclusive New Defenses

🏰 Spell Tower (×2) — TH15 Exclusive

Arguably the most impactful new defense at TH15. You build two of them, and each can be loaded with one of three spells for defensive use: Invisibility, Rage, or Poison. A Poison Spell Tower shreds kill squads. A Rage Spell Tower boosts nearby defending troops into a nightmare for attackers. They reach Level 3 at TH15 with 3,100 hitpoints and fundamentally change how attackers must approach your base — they can no longer ignore defensive spell coverage when planning funnels. Supercell introduced both the Spell Tower and Monolith in the official TH15 launch as the defining defensive additions of this Town Hall level.

💀 Monolith (×1) — TH15 Exclusive

The Monolith is a single-target defense built and upgraded with Dark Elixir — it deals massive damage to individual units, making it devastating against heroes and high-HP troops like Golems and Electro Titans. At Level 2 (max at TH15), it has 5,050 hitpoints. Properly positioned in the core of your base, it can neutralize kill squads before they reach your Town Hall. It’s the closest thing CoC has to an anti-hero defense.

New Troops & Spells

Unlock	Type	Why It Matters
Root Rider	Ground Troop	Dominant at TH15 — attacks walls and passes through them. Cornerstone of current ground meta.
Dragon Rider	Air Troop	High-damage air unit. Core of Dragon Rider + Inferno Dragon air strategies.
Electro Titan	Ground Troop	Massive HP tank (Level 3: 7,200 HP). Absorbs enormous damage while your army pushes the core.
Recall Spell	Spell	Pulls troops back into a Siege Machine — high skill ceiling, high reward for repositioning.
Revive Spell	Spell	Temporarily revives a fallen hero — strong pairing with Archer Queen and Royal Champion walks.

The 2026 Addition: Dragon Duke at TH15

As of March 1, 2026, TH15 got significantly more powerful on the hero front. Dragon Duke — CoC’s 6th hero and second aerial unit — unlocks at Hero Hall Level 9, which requires TH15. This means TH15 is now the first level where you can field a full six-hero roster. Getting Hero Hall to Level 9 is a meaningful 2026 priority that didn’t exist before March. Supercell announced and detailed the full Dragon Duke release on the official Clash of Clans blog alongside the February 2026 update patch notes.

📌 2026 Context: Dragon Duke’s passive ability (Royal Rampage) doubles his damage and adds 50% attack speed when no air units are within 6 tiles. At TH15, base defenses don’t hit hard enough to shut him down quickly — making him more impactful here than at higher Town Halls. Unlocking him early is a genuine competitive advantage in war.

Day 1 at TH15: Your First Builder Assignments

The first 24 hours at TH15 set the tone for how functional your base will be during the weeks of upgrading ahead. Two builders have clear, non-negotiable assignments. The rest follow a tight priority order.

Builder 1 → Build Monolith

Start construction immediately. The Monolith costs Dark Elixir and is one of the most threatening defenses your base gains at TH15. Every day it’s not on the map is a day attackers don’t have to plan around it. Once built, keep upgrading it to Level 2.

Builder 2 → Spell Tower #1

Begin construction on the first Spell Tower. Once done, immediately start the second. Two Spell Towers alone are enough to deter most TH14 attackers from your base while the rest of your upgrades catch up. Load them with Poison Spell for maximum kill-squad disruption.

Builder 3 → Laboratory

Use a Book of Building here if you have one — this immediately opens your Lab queue for TH15-level troop upgrades. Root Rider and Dragon Rider upgrades should be your first Lab targets. Missing Lab time is the most invisible cost in progression.

Builder 4 → Army Camp

TH15 Army Camps give +20 housing space total. More housing space directly means more Root Riders in your army, which translates to stronger attacks immediately. This upgrade pays off in every single raid.

Builder 5 → Barracks

Barracks Level 17 unlocks Root Rider. If Root Rider isn’t available in your army yet, this is the bottleneck. Upgrade it early. Once Barracks is done, this builder moves to Gold Storages so you can accumulate enough resources for the defense queue.

Hero Upgrade Priority at TH15 (Including Dragon Duke)

All four original heroes gain 10 new levels at TH15. The temptation is to focus on one hero — resist it. Upgrading heroes in parallel keeps your attack options broader and avoids long gaps where your best hero is unavailable for war.

Core Hero Upgrade Order

🏹 Archer Queen + Grand Warden — First Focus

Upgrade these two together as your primary hero investment. Archer Queen at Level 85 and Grand Warden at Level 60 is a solid functional target before shifting to the others. Queen Walk and Warden-supported pushes are the backbone of TH15 ground strategies — both heroes carry attacks more directly than King or Champion at this level. Bringing Archer Queen to TH15’s cap unlocks the Eternal Tome equipment level, a significant aura upgrade.

⚔️ Barbarian King + Royal Champion — Second Wave

Once Queen and Warden are at workable levels, shift Dark Elixir to the King and Champion. Royal Champion’s Recall Spell and Wall Wrecker synergy makes her increasingly valuable at TH15. Barbarian King remains the tanking anchor for ground pushes — his upgrade levels affect his Iron Fist recovery, which directly impacts whether your ground army survives into the base core.

🐉 Dragon Duke — Unlock Early, Level to 5 First

Hero Hall Level 9 is your gateway to Dragon Duke. Prioritise getting Hero Hall to Level 9 before you’ve maxed your other heroes — the sooner he’s in your roster, the sooner you can run two-lane hero dive strategies. Once unlocked, get him to Level 5 minimum — the stat jumps in the first five levels are significant. Then level Fire Heart equipment immediately (his only HP regeneration source, since Healers don’t target him). A Level 5 Duke with maxed Fire Heart already contributes meaningfully to TH15 air attacks.

⚠️ Don’t max one hero at the expense of others: A Level 90 Barbarian King with a Level 65 Archer Queen is weaker than both at Level 80. Hero synergy matters — you’re building a team of six, not a single carry.

Pets at TH15 — Four New Unlocks

TH15 unlocks four pets via the Pet House: Frosty, Phoenix, Diggy, and Poison Lizard. The Pet House needs four separate upgrades to unlock all of them — each upgrade takes Builder time, so sequence matters.

Pet	Best Paired With	Why	Priority
Frosty ❄️	Barbarian King / Archer Queen	Slows defenses + spawns Frostmites that absorb damage. King with Frosty tanks through compartments effortlessly.	1st
Phoenix 🔥	Barbarian King / Archer Queen	Revives the hero briefly after death — those extra seconds of invincible hero time frequently decide whether an attack 3-stars.	2nd
Diggy 🪨	Royal Champion	Tunnels underground and stuns its target on first hit. Particularly effective against Monoliths and Inferno Towers.	3rd
Poison Lizard ☠️	Any hero	Spawns Boogers that distract defenses and soak hits. Useful but less impactful than the top two — still worth upgrading.	4th

Defense Upgrade Priority: What to Upgrade and What to Skip

After building Monolith and Spell Towers on Day 1, the rest of your defense queue follows a clear value hierarchy. Not all defenses are equal — and at TH15, some are dramatically more impactful than others given the current attack meta.

Tier 1 — Upgrade Immediately

Eagle Artillery

The highest single-defence threat in your base. Eagle Artillery targets the troops that have been deployed the most — meaning it fires on your opponent’s army at the worst possible moment. Its new TH15 level adds meaningful damage and HP. Always upgrade this first in your regular defense queue.

Scattershots (×2)

Reach Level 4 at TH15 with 5,100 hitpoints. They deal splash damage to air units from long range — directly countering Dragon Rider and Dragon-based strategies that dominate TH15 war attacks. In the current air-heavy meta, upgraded Scattershots are non-negotiable.

Spell Tower → Level 3

You built them on Day 1 — now upgrade them to Level 3. The HP increase keeps them alive long enough to cycle through their spell charges during an attack. Poison Spell Tower remains the strongest general-purpose loading given how much CWL relies on hero kill squads.

Tier 2 — Upgrade Next

Inferno Towers (×2)

Reach Level 9 at TH15 with 3,700 HP. They’re your answer to tanky heroes and high-HP troops. Multi-target Infernos counter Dragon Duke specifically — experienced TH15 players already position them on the perimeter to deny Royal Rampage. Set at least one to Multi-target mode.

X-Bows (×4)

High-DPS ground defenses that punish Root Rider smashes when positioned well. TH15 gives them a new level — worth upgrading after Infernos but before the lower-tier defenses.

Air Defenses (×5)

Reach Level 13 at TH15 with 1,700 HP. In an air-heavy meta, upgraded Air Defenses disrupt Dragon Rider pathing. At minimum, upgrade them to their TH14 equivalent level before worrying about Cannons or Mortars. The Dusk guide notes Air Defense as the standout high-value regular defense at this TH level.

Tier 3 — Fill with Remaining Builders

Wizard Towers, Archer Towers, Hidden Teslas, Cannons, Mortars, and Bomb Towers all receive one new level at TH15. Upgrade them in roughly that order — but only after everything in Tiers 1 and 2 is done. These defenses rarely determine whether an attack 3-stars at this level; the Monolith, Spell Towers, and Infernos do.

💡 Skip for now: Resource Collectors (Gold Mine, Elixir Collector, Dark Elixir Drill) have no new upgrade levels at TH15 — you don’t need to touch them. This saves meaningful Builder time. Similarly, Traps can wait until all defenses are done.

Laboratory & Hero Equipment: 2026 Priority

Your Lab runs in parallel with the Builder queue — never let it sit idle. The troop upgrades you choose in the first weeks directly determine which attack strategies are available to you at full strength.

Lab Priority Order

Troop / Spell	Priority	Reason
Root Rider	Highest	Dominant ground troop at TH15. Higher level = more survivability in Root Rider smashes.
Dragon Rider	Highest	Core of TH15 air attacks. Pairs directly with Dragon Duke for two-angle pressure.
Electro Dragon	High	Strong in Electro Dragon spam strategies. Higher level increases chain damage output.
Electro Titan	High	Massive HP tank for Super Witch Smash and Golem-based strategies. Level 3 = 7,200 HP.
Super Witch (via Witch)	High	Super Witch Smash remains reliable at TH15. Witch upgrades feed directly into Boosted form power.
Miner	Medium	TH15 gives Miner two upgrades (the only troop with double upgrades here). Worth doing eventually.

Blacksmith Level 8 — Don’t Overlook It

TH15 upgrades the Blacksmith to Level 8, which unlocks three new levels for Epic Equipment across all heroes plus the Haste Vial equipment piece. The Epic Equipment level increases are the real value here — maxing your Giant Gauntlet or Frozen Arrow to their new Level 27 caps meaningfully boosts your hero’s performance in attacks. Upgrade Blacksmith early and keep ore farming active throughout TH15.

For a full breakdown of which equipment to prioritize across your entire hero roster — including the new Dragon Duke gear — see our Hero Equipment guide and the CoC Ore Farming guide for keeping your upgrade pipeline funded.

Walls & Resource Buildings: What the 2026 Meta Means for Them

Walls are a perennial question at every Town Hall level. The short answer at TH15: they matter less than they used to, and you should deprioritise them relative to everything else covered above.

The reason is structural. Two of the strongest attack types at TH15 — Root Rider smash and Dragon Rider air strategies — effectively bypass walls. Root Riders tunnel through them; air attacks fly over them entirely. Spending Gold on walls while your Inferno Towers and Eagle Artillery are still at TH14 levels is a poor trade. Upgrade walls with overflow Gold after your core defense queue is running, not alongside it.

📌 Practical wall target: Aim for roughly half your walls at TH14 level and half at TH15 level while your defenses are upgrading. TH13-level walls at 11,000 HP are still adequate for compartment integrity — don’t feel pressure to rush walls to max while builders are occupied with higher-impact upgrades.

Resource Buildings: Gold Mines, Elixir Collectors, and Dark Elixir Drills have no new upgrade level at TH15. You don’t need to touch them — this is a meaningful Builder time save. Gold and Elixir Storages do receive an upgrade, and getting those done early helps you accumulate enough resources for the heavy defense queue.

Complete TH15 Upgrade Priority — Summary Checklist

For easy reference, here’s the full priority order consolidated. This sequence assumes you’re playing actively and have five builders available.

Phase	What to Upgrade	Notes
Day 1	Monolith → Spell Tower ×2 → Lab → Army Camp → Barracks	Use Book of Building on Lab to open troop queue immediately
Week 1–2	Gold Storages → Eagle Artillery → Scattershots → Hero Hall L9	Hero Hall L9 unlocks Dragon Duke — 2026 priority
Ongoing — Heroes	AQ + GW together → BK + RC → Dragon Duke to L5	Never max one hero while others are far behind
Ongoing — Lab	Root Rider → Dragon Rider → Electro Dragon → Electro Titan	Never let Lab sit idle
Week 3–4	Spell Tower → L3 → Monolith → L2 → Inferno Towers → X-Bows	Multi-target Inferno counters Dragon Duke — key in 2026
Mid-term	Air Defenses → Wizard Towers → Archer Towers → Hidden Teslas	Air Defenses first given current air-heavy meta
Later	Cannons → Mortars → Bomb Towers → Traps	Low impact on war performance — finish last
Fill with Gold	Walls (half to TH14, half to TH15 levels)	Lower priority — Root Rider + air attacks bypass walls anyway

Frequently Asked Questions — TH15 Upgrade Priority

What should I upgrade first at TH15?

Build the Monolith and both Spell Towers on Day 1 — these are TH15 exclusive defenses that immediately change how attackers approach your base. Simultaneously start the Laboratory upgrade (use a Book of Building if available to save time), an Army Camp for housing space, and Barracks to unlock Root Rider. These five assignments on Day 1 set you up for the first month efficiently.

Should I unlock Dragon Duke at TH15?

Yes — upgrading Hero Hall to Level 9 to unlock Dragon Duke is a meaningful 2026 priority at TH15. He’s the only Town Hall where you can field the full six-hero roster, and at TH15 specifically, his Royal Rampage is more impactful than at higher levels because defenses don’t hit hard enough to counter him quickly. Get him to Level 5 and max his Fire Heart equipment as soon as possible after unlocking.

What’s the best Spell Tower loadout for defense at TH15?

Poison Spell is the most broadly effective defensive load in 2026. It shreds kill squads — hero groups, Minion Prince dives, and Queen Charge combinations — which are the primary threat against most TH15 war bases. Rage Spell Tower is a strong alternative if your Clan Castle troops are powerful and positioned near the Tower, since it boosts them into a serious defensive threat. Invisibility Spell Tower has more niche value and is generally less reliable on defense.

How important are walls at TH15?

Less important than at lower Town Halls, given the current meta. Root Rider — one of the dominant TH15 troops — passes through walls. Air strategies bypass them entirely. Walls are still worth upgrading as a long-term Gold sink, but they should never compete with active defense or hero upgrade timers. Aim for a mix of TH13 and TH14 wall levels while your main upgrades are running, then fill them in with overflow Gold later.

Which pet should I unlock first at TH15?

Frosty is the highest-priority pet unlock at TH15. Paired with the Barbarian King or Archer Queen, his freeze effect and Frostmite spawns make the hero significantly harder to stop during a push through the base core. Phoenix is the second priority — the revival effect during hero ability use is one of the most attack-deciding mechanics in war at this level.

What new troops does TH15 unlock?

TH15 unlocks Root Rider (via Barracks upgrade), Dragon Rider, and Electro Titan as new troops, plus Recall Spell and Revive Spell as new spells. Root Rider is the most immediately impactful — it passes through walls and deals high damage to buildings, making it the cornerstone troop for ground smash strategies at TH15 and above.
