[RPG] When do you roll the damage for Cloud of Daggers

damagednd-5espells

The cloud lasts up to 1 minute, and specifies 4d4 damage. Is the damage rolled when you cast it, or is it rolled each time an enemy is afflicted by the cloud?

Best Answer

A creature takes 4d4 slashing damage when it enters the spell’s area for the first time on a turn or starts its turn there.

This 4d4 damage is per time affected (and per creature), not once for the spell. You do not roll once when casting the spell and then deal the same damage to the affected creature each time the spell deals damage; you roll once for each instance of damage. This is true for almost all methods of dealing damage.
