Without thrasher... He's impossible. You walk in, he pops out of his tiki statue, then he does some magic trick and you die. Instantly. I died 12-15 times, along with my group. We finally quit.
The next day, just to try the boss with a thrasher group out, I bought thirty platinum (Thrasher was DOTD) to get thrasher.
The group beat him in 20 seconds. Uh, for the players who don't have platinum 100% of the time, could you ease up on us?
