Spellwarp: Ethereal Magic (GEP)

__TOC__
It seems a body can't go anywhere on the planes without magic turning upside down and inside out. Wizards who make extended crossplanar trips need to tumble to the whys and wherefores of planespecific magic pretty quickly if they don't want to end up in the dead-book. The Ethereal Plane is no exception; some types of magic and magical items are diminished or don't work at all, while other sorts are enhanced. 
Those who believe the chant that the Ethereal is the plane of possibility are not too surprised to learn that magic dealing with creation is more effective than magic from other schools, while some magic-especially spells related to divination-don't seem to function. 'Course, some 'slingers are lucky enough to chance upon spell keys that allow them to cast all types of spells on the Ethereal. Unfortunately, access to these keys (whether physical or purely mental) is limited by their extreme rarity.
A priest, on the other hand, doesn't have to worry about the Ethereal's warping effect; her spells remain untouched by the plane. 'Course she still has to deal with the fact that her power's probably a few planes away, limiting her ability to channel spells. All in all, a spellcaster'd better choose and use her spells wisely, as they could mean the difference between life and death.
