My first try I did it with the Witcher SNS and couldn't keep the Pukes alive. It also took forever to kill anything with it. Second time I decided to go for the SA and was tearing up everything. The Gajalaka sidequest was stupid easy, the Jagras packs got tore up and even the tree boss was stun locked most of the fights. Until I get to that last pukey part again and I couldn't even touch the damn boss. His attacks just seem faster and more likely to stun in that part, spent half the fight in the air and the other dazed.
Gonna give him another go until I get it done, but i'm gonna loathe doing this fight again for my alts.
