Demon Brothers 3 pet skill

I moved my 3 demon pets from my Dual Blade to my Dark Knight, and I got hte quest from Metus for the skill. I read through his text, and went to go find his NPC, but I cant find it. I can't equip my three demon pets. When I did the quest on my Dual blade, i went and talked to the Metus NPC and he gave me the three pet skill.

So I cant find metus. Did they remove him and the free 3-pet skill thing that came with the demons? Or is Metus located somewhere else now? Do I have to buy that pet skill thing in the cash shop?

You mean the Pet Snack? Yes you do.

Did you accept the quest and find the hidden note near the npc at the top in hene park? I think you needa do that now.
