Prerequisite: Ability to cast base cost 5 spells
Effect: So long as you have at least 5 MP conserved and know a spell of the Earth descriptor, you can create a small burrow three to five feet deep in the land, with a small wall that surrounds it which can provide cover for creatures within. Entrench cannot be used to dig through walls or foundations (although it could burrow around them) nor can it rearrange magically treated terrain. Entrench affects one 5ft square + one additional 5ft square per 2 MP you have conserved. These squares do not have to be contiguous, but no two squares may be more than 30ft apart. This feat can only affect terrain with a hardness of 0.
If the area of effect completely contains a creature’s space, including yours, that creature must make a Reflex save or fall prone in the burrow. If a creature happens to be burrowing in the area of effect and would be exposed by this feat, it emerges prone, but unharmed, in the trench.
