The adventure I am running has the following trap:
Continuous Magic Missile Trap: CR 5; Proximity trigger; automatic reset; 3d4+3 damage automatically, each round, no save; Search DC 29; Disable Device DC 29
The player find the trap and then cast Dispel Magic on the area.
There are no rules I can find for if this should work. The player rolled very high on Dispel Check, as I guesstimate that the Caster Level was about 8.
Are there any real rules and can you do this with Dispel Magic?
