Traits and special behavior

Three strikes. Atir avoids the previous random target when another is eligible.

Furnace Breath. On rounds 3, 6, 9 and every third round thereafter, Breath replaces the entire action. Each living hero receives an independent Fire damage roll with Burning. A telegraph warns of the coming breath. Exact dice and tier-specific profiles are retained in the configuration below.

Final modifiers. Maximum HP is multiplied by 0.85 after tier scaling and rounded up. Outgoing damage is multiplied by 0.75 once, including Breath. Burning uses the already-reduced actual hit. Atir is immune to Polymorph.

See the condition reference for the shared effects, and enemy tuning for difficulty-wide chance adjustments.
