I am a recent returnee played for years and started a new character on vox. I remember a certain AA I used to have that would allow People to cast group buffs on my pet but I can’t seem to find it. I think it was called pet affinity. I am a necro if that helps.
It was pet affinity and it was consolidated Pet Affinity to be a rank of Suspended Minion and renamed the line Companion's Suspension.
