Deathward Armor

Armor (light, medium, or heavy), very rare (requires attunement)

This armor is decorated with etchings of coffin-shaped shields and grants you a +1 bonus to AC. While wearing this armor, when you are reduced to 0 hit points, you can use your reaction to drop to 1 hit point instead and also gain 3d6 temporary hit points. Once this special reaction is used, it can’t be used again until the next dawn.
