Your Castle wall is both your health bar and your deployment capacity limiter. Early Gold should always prioritize Castle Level milestones that open new Hero deployment slots before you invest heavily in flat HP scaling.
Upgrading the Castle scales base wall HP and progressively unlocks up to 9 simultaneous Hero deployment slots alongside 1 Field Captain lane slot, 3 Cannons, and elemental Turrets. The cap expanded from Lv. 70 in early Playtest to Lv. 150 and finally Lv. 300 in the v1.0 launch build.
All battle EXP earned from wave clears flows into the Training Grounds to raise global Castle combat power. Once standard Training tiers are completed, two Peak Training branches unlock—scaling up to Lv. 1,000 for massive endgame damage multipliers.
Spend Talent Points across Economy and Combat branches. Rush Mining Efficiency and Summon Count nodes first so your passive Gold/Diamond income and active projectile count compound throughout the first 1,000 waves.
Recruit Heroes, Captains, and Turrets at the Tavern using Diamonds and Vouchers. Duplicate pulls convert into character Shards for promotions up to 10 Stars. The November 4, 2026 patch added a one-click Batch Star-Up button to eliminate manual clicking.
The underground Mine beneath your Castle operates continuously online and offline. Understanding the division between Human Miners and Orc Miners—especially after the November 4, 2026 economy patch—is essential for sustaining Tavern 10-Star pulls and Black Market blind boxes.
