Life Shell (PEACH)

[ShriekingDrake]

Here's a somewhat more powerful, higher level complement to Antilife Shell that works on the creatures Antilife Shell does not cover.  What do you think about this? . . .

Life Shell
Abjuration
Level: Clr 9, Drd 8
Components: V, S, DF
Casting Time: 1 round
Range: 10-ft.
Area: 10-ft. radius emanation, centered on you
Duration: 10 min./level
Saving Throw: None
Spell Resistance: Yes (see text)

You bring into being a mobile, hemispherical energy field that prevents the entrance of most types of unliving creatures. 

This effect hedges out constructs, elementals, outsiders, and undead, including those creatures otherwise immune to magic and unliving incorporeal creatures. These unliving creatures may not enter the shell. Those within the shell are bolstered with a sense of calm such that abilities and effects that cause fear or that would compel or cause creatures within the shell to leave the shell do not affect creatures within the Life Shell.

Casters add their wisdom modifier to spell resistance rolls against constructs and undead.

This spell may be used only defensively, not aggressively. Forcing an abjuration barrier, such as Life Shell, against creatures that the spell keeps at bay collapses the barrier.
