Yeah, he seemed to be focusing on the rock beetles, in those battles. He also seemed to forget some of the characters, at times. Was it the rogue that was left idling most of the time?
The rock beetles are burly, but that wood beetle poison will kill a character pretty quickly. If a few of your party members get poisoned it can be tough to recover. We may end up toning it down depending on feedback from the beta.
In IE games, poison was one status effect that, if you weren't hauling around antidotes or cure poison scrolls, could easily wipe out your party. I specifically remember a spider infested house in Beregost for example.
How many ways are there to deal with poison in PoE?
