For me Slag..
I like Grimm and orion for wt4
grimm for as he has almost the same stats as slag but it was free pet with event
orion for his dmg reduction and 160 extra health
but also shadowlurk / gyrm and ethl are good pets for wt.
Glowstick! Raw damage stat is awesome and the AA rocks the mausoleum.
" BRAINS ARE AWESOME!!!! I wish everybody had one..."
