I have a couple questions about pets that hopefully somebody can answer... I tried searching through the forums and couldn't find the answers I needed. Do pets gain all the perks from the armor/weapons you put on it (Including stat increases/augments/soul crystal abilities)? The "Pet Weapons" that increase dmg for the pet, are they worth using? How much does it increase P Atk/M Atk? Or is using a higher grade, non-pet weapon better?
