About
Blood magic is a skill and a weapon class in Valheim which was added in the Mistlands update. As one of the two types of Magic, it affects the amount of damage dealt by blood magic summons, the amount of Eitr used to cast blood magic, the amount of health drained by casting blood magic, and various other factors.
At blood magic level 0, the base values for health drain, and eitr are used. At level 100, health drain and eitr usage are each reduced by 1/3 of their respective base values.
The damage dealt by creatures summons with blood magic weapons is also affected by skill level, with the only example so far (the Dead raiser) ranging from 100% damage at blood magic 0 to 300% damage at level 100.
Blood magic skill also affects the maximum amount of damage which can be absorbed by the Magic Barrier produced by the Staff of protection, with a base value of 200 damage at level 0, increasing by 5 per level to a maximum of 700 damage at level 100.
