Found the funniest way to beat Anders (Paladin of Tyr)
Spoilers, I guess?
Prepped the battle space by covering both exits on the ground floor with grease. Took out the girl on the deck (after trading to her the severed limbs I found laying around for some healing potions). Anders comes running (trying to run, anyhow) at me. Slips and falls on his ass. Wyll with Eldridge blast, knocks him back further, Karlach blinds him with wild magic. Anders runs at me again, slips and falls on his ass. Eldridge blast, me laughing so hard I can barely see the screen. After 3 times he tries running around to the other door. Falls on his ass. Eldridge blast one last time, then Astarion sneak-attack ranged for the kill. Homeboy spent 90% of the time on his ass, never dealt a single point of damage.
At this point I'm laughing so hard I am snorting uncontrollably, my kids laughing like Tasha's Hideous Laughter was an AOE spell. 11/10, would do again.
