Chamber of the Earthbound

Within the walls of this chamber, the fly spell does not function, nor does the flight function of any magic item that has fly as a prerequisite. Characters flying before entering the chamber float to the ground as if the spell’s duration had expired. Upon leaving the chamber, any fly spells or effects whose duration has not expired returns to normal efficacy.

Caster Level: 7th; Prerequisites: Craft Wondrous Item, spell immunity; Market Price: 14,000 gp.
