Missing Chamber

This stronghold space—and everyone and everything inside it—is difficult to detect by divination spells, detect spells, and magic items that mimic these effects. For such a spell or item to work, the caster or item must succeed at a caster level check (1d20 + caster level) against a DC of 16.

Caster Level: 5th; Prerequisites: Craft Wondrous Item, nondetection; Market Price: 7,500 gp.
