I wanna share a lamer, cheap and pathfinding abuse technique to beat dallis in fort joy. It requires teleport, a decent physical dps character and...a lot of stools.
Put the stools in front of the two main ladders for the alternative entrance of fort joy.

I put some barrel and boxes even on the staricase near the cardplayers scum.
The strategy is simple, just teleport one enemy at a time, and focus your dps on him. Once killed, repeat the process.
It's kinda a cheat/abuse, i know, but it's fun laugh

The best part of the fight was the magister archer trying to beat one stool XD
