- Not to be confused with Gurtogg Bloodboil.
It deals 70% less damage in PvP.
- Prior to patch 3.1.0, Blood Boil did no damage to targets with no diseases on them. Hence one would first stack the target with diseases, then use to spread them to nearby mobs and then use Blood Boil. Until patch 6.0.2 this was still an effective method of boosting Blood Boil's damage, however it could still be used to do some damage even to undiseased enemies. Using Blood Boil in this fashion was primarily useful when tanking or for killing swarms of low-health targets.
Tips and tactics
- As a tank, Blood Boil is very useful for picking up stray mobs while your other AoE abilities are on cooldown.
