I was accidentally the VIP of an encounter when I wasn't even there. I had cast Heroes' Feast at the start of the day during our previous session. Then I was missing from the table for some reason at the next session. But there was a great big fight the DM had surprised the party with against an ancient Green Dragon. Two of the effects of the Heroes' Feast is immunity to fear bye-bye dragon fear and immunity to poison bye-bye dragon breath. Totally nerfed the dragon without meaning to. It was no doubt divinely inspired by my cleric's deity.
