Triton

Strategy: Triton is the defining Infantry rally lead of the Gen 6 era, and the reason is almost entirely Tidewill: a full two seconds of invulnerability before he unloads Attack × 140% AoE damage. In practice that window absorbs the opening burst that would otherwise wipe your Infantry stack before the fight even develops — the single biggest cause of lost rallies against a well-set garrison is losing your lead hero in the first exchange, and Tidewill removes that risk almost entirely. Regal Wrath then compounds the payoff, stacking +24% Attack and +48% Defense for four seconds right as the invulnerability ends, so Triton is hitting harder and tanking better at exactly the moment he becomes vulnerable again. Skill priority: max Tidewill first — the invulnerability duration doesn't scale, but the damage does, and it's your primary source of burst. Regal Wrath second for the survivability curve, Striking Hit last since its 28% proc is passive value you'll get regardless. For composition, pair Triton with Thrud (Cavalry) and Vivian (Archer): Thrud's Ancestral Guidance buffs the whole army every four Cavalry attacks, and Vivian's Crouching Tiger permanently amplifies enemy damage taken by 25% — both stack cleanly with Triton's own tankiness rather than competing with it. This is currently the strongest three-hero core in the game, and it's worth building gear priority around getting all three online rather than over-investing in any single one first.
