Tips and tactics

• As a tank, Blood Boil is very useful for picking up stray mobs while your other AoE abilities are on cooldown.

Notes

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 Pestilence to spread them to nearby mobs and then use Blood Boil. This is still an effective method of boosting Blood Boil's damage, however Blood Boil can now be used to do some damage even to undiseased enemies. Using Blood Boil in this fashion is primarily useful when tanking or for killing swarms of low-health targets.
