I don't believe HeRO has messed with Pet Abilities at all.??Everything should be default as found on Gravity.
Custom pets don't have abilities either.??Here's a list that I believe should be correct, even though I usually don't own pets for their skills >_> If the list is wrong I'll just take it out since I stole it from some site.
