Building Requirements to Train T10 Troops

Laboratory Lv 30HQ Lv 30Barracks Lv 30

All three buildings must reach Lv 30 before T10 troops can be trained — even after the Unit Special Training research is complete.

Priority node: Recharge Shield

Recharge Shield (Phase 4, 219,000 badges / 20 levels) grants +50% Troop HP — the single most powerful buff in the entire tree. Even partial levels provide significant HP scaling that multiplies with your base defense. Invest here as soon as it unlocks — do not skip to Unit Special Training immediately.
