I was in a hard VoD run yesterday and I was using both Mass Hold and trying to use the AM Hypno SLA. I have a 42DC for enchantment spells. The bearded devil mobs appeared to be failing their saves to mass hold almost universally, yet when I cast Hypnotism, they almost universally saved.
I checked to make sure that heighten was activated and it was, so I'm wondering if it's not working properly on SLAs. Sadly, since it's an enhancement not a spell, I couldn't mouse-over for the DC.
Has anyone else noticed this?
