Demonic Shield

Demonic Shield is a 1-cost Uncommon Skill card for the Ironclad that causes you to lose 1 HP and gives another player Block equal to your current Block. In multiplayer Slay the Spire 2 co-op, this is a powerful support card that lets the Ironclad protect allies.

Demonic Shield's HP loss triggers Rupture for Strength, Crimson Mantle for additional Strength and Block, and Inferno for AoE damage. In a Barricade deck, your persistent Block can be massive, making the copied Block equally large. Pair with Impervious or Tank for maximum Block to share. The Ironclad's high Block generation through Shrug It Off, Flame Barrier, and Blood Wall makes the shared Block substantial.

Demonic Shield is the Ironclad's team support card for co-op play with the Silent, Defect, Regent, or Necrobinder. Pick it in multiplayer when your allies need Block support. Against bosses like Doormaker that deal AoE damage to all players, sharing your Block is extremely valuable. In solo play it has no target, so it is only useful in co-op. The Ironclad's natural Block-building capability makes it the ideal character to share defenses.
