Additionally, enemies target player characters using concentration spells. This can be exploited since they avoid hitting high AC characters otherwise.
However, it may still cause concentration spells to suck in boss fights for glass canon builds. Certain play styles, like any warlock relying on hex, attract disproportionate attention.
Ethel having it out for Wyll confused me in my first playthrough. At that, I was level 3. It took being chased around by a tadpole wildshaped druid to cut that aggro. She's apparently coded to hate that, which is funny, because a crit from her claws could one shot anyone. And she kept critting. That boss is even more dangerous at melee distance.
To be fair, they seem to focus on low HP characters, too. That helps front line classes balance it out /if/ everyone else is at full HP. As a hidden con, it makes builds featuring one damage sink unviable for me. Once they're down, it's an endless revival/death loop. Not that you couldn't exploit that occasionally. It's just not great fun.
It definately used to be the case that enemies avoided attacking high AC characters but I think Larian changed this at some point. At least it doesn't seem to be the case currently.
Do enemies prioritize characters using con spells? I've not really noticed this one way or another.
I agree they target low HP characters, a good strategic option for the AI (and the player)
