Charles

Strategy: Charles is the current standard for defensive Infantry, and one skill explains why: his exclusive Mechanic skill restores 35% of his Max Health the first time he drops below 50% HP in a battle, then increases his Defense by 30% for the rest of the fight. That's a once-per-battle safety net that fundamentally changes how a garrison fight plays out — the enemy has to burst him down twice, not once, and the second time he's hitting harder and tanking better than the first. Vengeance and Parting Gift are both AoE (Attack × 140% with a 1s stun, and Attack × 280% on his mech's destruction), so he's not purely passive — he deals real damage even while playing the anchor role. Great Justice's +25% squad Health on top of Iron Bodies' -20% damage taken means the squad around him benefits from the same durability philosophy. Skill priority: Mechanic (his exclusive) is what defines the build — prioritize unlocking Justice Fist as soon as possible. Among conquest skills, Vengeance first for the stun, then Parting Gift, then Nimble Soul. He's rated S-tier for Garrison specifically — his kit is not built for Rally Lead or Bear Hunt, so don't force him into those roles.
