THE BATTLE. There's a giant undead beholder monster on the loose. Do you try to join in on the fight and help? Are you stuck with someone else's body and powers? Man, that's going to make things tough.
Magic users, the beholder can create an anti-magic area of effect, so your spells may or may not come through all the time. That's gunna be frustrating (but it can interfere with the beholder's own magical abilities as well).
Do you face the monster? Run away? Get hit with a legendary ability? Put that here.
