help in pet making

Hi everyone,
I'm seraphinefia, a rogue in the game.I recently got a heroic wylenor from the event. I like it's happiness bonus considering how it gives 50+stats damage and crit too. but I was thinking of changing its arcane ability.I was considering cottonkill's shield since I die a lot. So can anyone give best options for AA and I know u change the ability using story token by opening slot but can anyone give me some tips on that too.

Yeah best AA for rogue*

The biggest cost is opening the slots, at 50 Story Tokens. After that, slotting is I believe no cost and unslotting costs just 5 Story Tokens. A few hundred Story Tokens lets you try many pets. You might also try Venim's aa, but yeah, Cottonkill is very useful.

Okay so venim. I'll try that. Thanks
