Known bugs:
* aff spec aura doesnt apply to pets
* felguards 10% more multiplier only applies to autoattack damage, not special attacks(felstorm,legion strike)
* PS ST DoT cannot crit, but the AoE ticks can crit secondary targets.
* Seed of Corruption doesn't deal damage or apply corruption if detonated while the player is stunned.
* When tyrant spawns during the 5th cast of an imp, the imp bugs and despawns.  The resource cost isn't canceled, the imp hits 0 energy, tries to cast again because it costs nothing, and then despawns anyway. Pip seems to think that its because the cost prevention from tyrant is calculated at the start of an imps casti nstead of the end.
* vilefiend, when summoned at 40 yards, spends 2 seconds walking forward before it bile spits and leaps. The range on spit appears to be 35 despite spelldata saying 40.
* vilefiend's bile spit dot cannot critically tick
* dreadstalkers are triggering an old artifact trait without the artifact equipped. sharpened dreadfangs, supposed to give 10% crit to them. they dont appear to benefit from it, but felguard seems to have 10% higher crit than other pets?
* Inevitable Demise is applying to Drain Soul
* Implosion projectile is too slow and mobs moving sometimes do not get hit by it.
* Pets scale off haste twice for regen
* Tyrant isn't extending random demons
