[Tame Beast] All Damage mods do not apply to all damage.

The rare monster modifier All Damage Shocks/Ignites/Chills does not consider the Lightning damage from Mana Siphon/Lightning Damage aura modifier to be 'damage', and therefore does not apply shock/ignite/chill with its damage.

Maybe this is intended but the mod says "All" damage, not "Some" or "non modifier damage" lol.

It shouldn't say All Damage Shocks/Ignites/Chills then if not all damage does that then lol. Maybe "Shocks/Ignites/Chills on Hit" would be an appropriate phrasing. Game needs to be consistent with its wording because of how complicated the interactions get.

Besides that specific interaction though, I've discovered that even actual Hit damage from lightning storms, periodic elemental explosions, corpse detonations, etc also does not benefit from All Damage X mods.
