A Cost 1 permanent Power that at turn start loses 1 HP and gains 8 Block (10 upgraded). Block auto-stacks every turn, guaranteeing baseline defense without playing cards. 8-10 Block per turn is often enough to cover mid-to-late combat, especially when paired with Block builds or HP-consumption synergies. The 1 HP per turn isn't trivial over long fights, but paired with Blood Boil (HP loss → Strength), every turn also stacks Strength — a powerful synergy. Upgraded 10 Block per turn provides a very stable defense line; early deployment stabilizes combat-wide defense.

Deploy early to kickstart auto-Block stacking. Combined with Barricade (Block persists), 8-10 Block per turn keeps accumulating without fading, building a massive defensive wall in a few turns. With Blood Boil (HP loss → Strength) in play, Crimson Robe's 1 HP per turn also grows Strength, scaling offense and defense together. Juggernaut (Block gain → damage) adds passive damage each turn, creating an attack-defense hybrid style. HP-consumption decks (Bloodletting, Offering) that already manage HP minimize the risk.

• Barricade: Power preserving Block across turns. Crimson Robe's per-turn Block accumulates infinitely into an ultra-high wall.
• Blood Boil: Power granting Strength on HP loss. Crimson Robe's per-turn HP loss feeds per-turn Strength — offense-defense synergy.
• Juggernaut: Power dealing damage on Block gain. Crimson Robe's per-turn Block triggers automatic damage each turn.
• Body Slam: Attack dealing damage equal to current Block. Barricade + Crimson Robe stacks Block for massive Body Slam hits.
• Feel No Pain: Power granting Block on Exude. Combined with Crimson Robe's auto-Block, pushes Block totals higher.
