Fire Trap

This spell is the same as the fourth level magic-user fire trap spell (q.v.) except as shown above and for the fact that the material components are holly berries and a stick of charcoal to trace the outline of the closure.

The spell can be removed/negated by a dispel magic as is normal.

Any closable item (book, box, bottle, chest, coffer, coffin, door, drawer, and so forth) is affected by a fire trap spell, but the item so trapped cannot have a second spell such as hold portal or wizard lock placed upon it except as follows: if a fire trap/hold portal is attempted, only the spell first cast will work, and the other will be negated (both negated if cast simultaneously). If a fire trap is cast after a wizard lock, the former is negated, if both are cast simultaneously both are negated, and if a wizard lock is cast after placement of a fire trap there is a 50% chance that both spells will be negated. A knock spell will not affect a fire trap in any way — as soon as the offending party enters/touches, the trap will discharge. The caster can use the trapped object without discharging it. 

When the trap is discharged there will be an explosion of 5-ft radius, and all creatures within this area must make saving throws versus magic. Damage is 1-4 hit points plus 1 hit point per level of the magic-user who cast the spell, or one-half the total amount for creatures successfully saving versus magic. 

The item trapped is NOT harmed by this explosion.

There is only 50% of the normal chance to detect a fire trap, and failure to remove it when such action is attempted detonates it immediately. 

To place this spell, the caster must trace the outline of the closure with a bit of sulphur or saltpeter.

A dispel magic has the possibility stated to remove the fire trap. If it fails to do so, the trap is not affected and is not triggered.
