Dice rolls. Everyone gets attacked once. If you're hit, please make a Fortitude save and note the damage you took. It looks like Hannavrah is the only one against whom they rolled a 20. Here is the confirmation roll on that crit:
Rolled 1d20+9 : 7 + 9, total 16
Marlowe, Raoul, and Surin take the acid damage listed and also need to make Fortitude saves vs. the paralysis.
