There's a big rock head near the beginning that will flee when it gets low on health so kill it and you'll get a chest. Bees use final sting and will almost certainly kill you (sometimes you survive with very low HP). Our tank was hit for 2250 damage
Doom from first boss, stand on the platform that lights up to remove it. Also pops 2 bees every now and then
Move heads to platforms that light up and kill them there to pop open doors
Kill the heart of the golem and go nuts until heart respawns, rinse and repeat
Last boss pops a ton of fetter like things that spam laser beams that will *** you up. Also has a few pops that block out people when they start hitting it; a cage spawns around it. Think you need to pull the heads that pop to the squares (like before) and kill them. Boss also uses aoes so healer needs to avoid laser beams, avoid aggro, heal tank and heal DDs lol. It's fun.
I think there's a puzzle to open the boss door, you have to weigh things on the "scales of judgement" or something and if you get it wrong, mobs pop. Might pop a chest if you get it right?
