Mitch's Undersea Palace

Mitch's Undersea Palace

Mitch is a level 7 dwarf wizard, trying to build magic items he'll need to take on high-level foes and adventuring parties after his level. He normally keeps out of the way, but the local fishermen want him dead because he's summoning too many creatures to guard his undersea stronghold- and when there's bigger food, that draws krakens.

The coral walls on the outside slowly repair themselves, while the thin layers of lead in the walls prevent teleportation or scrying.
Mitch's Palace is designed to thwart teleporters who DO get in by having only a few areas not coated in lead- mostly flooded chambers that dimensionally anchor people and have a summoned octopus. Mitch lives in an obscure corner, with most of the dungeon being empty corridors filled with traps. The most devious is behind the rest of the dungeon, a set of two traps that summon a monster when a monster is summoned in their proximity. This results in fucktons of angry creatures knocking around his palace to deter intruders, and a virtually endless supply of crafting XP and seafood.
