How did you build your druid? I went half elf, dumped str and some int so i could get 16 dex, con, and wis. Cha was 12 i think. Ac actually seems to decent. They hit me less as a druid then in animal form. I actually been playing as a caster untill i take enough damage, then i wild shape and charge into the fray. Late game has been brutal though. Enemies all seem to have larger numbers and multi attack. As a dm...id never build encounters this way. Those minotaurs in the underdark are waaaay more powerful then they are supposed to be for a cr3 monster..and minotaurs are nasty encounters as they are. And they are making you fight 2 of them. Nasty. The kuotoa fight is kicking my butt right now.
