Mephit Portal

Mephit Portals are doors to the Elemental Planes that keep on summoning Category:Mephits until destroyed. They lack any defenses and have only 27 Hit Points, but are immune to magic.

Location
All four Portals present in the game can be found in Irenicus's Dungeon 2nd Floor. Each portal connects to a specific Elemental Plane and will summon a different subtype of mephit, though statistically, they are identical to one another.
