Threat: Tronk

[Chewi]

The last challenge I've left to do, and yet, I just can't beat more than half the life of the boss.
What am I missing? What's supposed to do?

EDIT: OK, I guess I know why, just checked a video on youtube, and the tronk takes a ridiculous knockback while it was a previous patch, and in my case it does not. So i guess one of the latest updates broke this challenge.

You’re supposed to use one of bandit’s abilities there to send a ton of attacks at it very quickly which can send it back

Finally got it with luck. It's all about explosive proc. Not much more to say about this challenge.

This is yet another hard challenge. I have the same problem with only getting him to 50% life with almost all skills aiming at him.
