Yeah, on my Warlock that part where you have to use Demonic Gate, it showed up as an extra button even though my char was only level 12.
OTOH, for Monk when I was doing the healer staff the final battle where you’re supposed to get a group of NPCs that you need to heal, it didn’t work.
The NPCs kept popping in and out of the group, and scattering all over the map so I couldn’t find them.
It took 4 or 5 tries before I could get them all in the same group and the same place at the same time and actually finish the battle.
