Aspect of the blurred beast gets boost w/shred vs poisoned, envenom boosts crits vs poisoned, you’re crits have % chance to reset companion, poison creeper active increases crit chance. So you could creeper, wolf active/shred, repeat. There’s other stuff too I’m sure I forget.
Imo, the issue is more the rabies doesn’t scale well (tbh it’s pretty garbage other than the debuff/envenom benefits), and Druid has too few slots for aspects/tempers.
