[Davros]

If your indoors the placement is a problem. The higher the power the more available height you need above you. Try loweriing the power you are casting at - need to do that first before you select a spot, because if you select a spot first it assumes you will be casting at max power available. If someone (party or enemy) moves into the space intended for the elemental, then he will be shifted off somewhere else. You can throw a canned elemental indoors with complete success however.
