Sorry if this is a little aged on the thread, but I have just encountered something that seems to contradict the 'one roll' rule. I am in 5E btw.
On Ortifex Blood Siphon from Tome of Beasts 2, in part:
"Each creature within 20 feet of the ortifex must make a DC 13 Constitution saving throw, taking 14 (4d6) necrotic damage on a failed save, or half as much damage on a successful one. The ortifex gains temporary hp equal to the single highest amount of necrotic damage dealt. If it gains temporary hp from this action while it still has temporary hp from a previous use of this action, the temporary hp add together."
Unless I am not seeing something, this wording seems to indicate that the AOE rolls are individual. Maybe this is somehow an exception to the general rule of 'one roll'?
Any thoughts?
