Pets and global accuracy
That's actually a pretty good question... I don't think pets or patches inherit any Accuracy or ToHit buffs that your character happens to have. However, they DO benefit from the Nerve line of Alpha Abilities, since those work on the same technical principle as Enhancements.
Pets don't inherit any set bonuses you have. Pseudopets (eg. Rain of Arrows) inherit any buffs you have, but I don't know about full pets.
Do pets such as Animated Stone benefit from my global accuracy bonuses from set IO's? I'm guessing not since it is a buff on the toon itself. Can someone please clarify this?
Does the same apply to Volcanic Gasses as well?
