The bot AI at its base level is only programmed to deal with the basic circle/cone/line AoEs from what I've observed. Anything else they'll either just eat it and start freaking out and moving erratically.

They sometimes attempt to counteract that by following another player, which is how they're able to trust farm Holminster Switch and a few other dungeons because the Scions will almost always guide them to safety.

I regularly see an entire party of bots that collectively farms instances for phatasmagoria mats on my server, though, so it seems like there really isn't much of a limit on what they're capable of if someone is has the know-how to write custom scripts for them.
