Siphon Spell Power Select Spell

Type of Feat: Class
Prerequisite: Ur-Priest 6
Benefit: Because they steal whatever power they can, ur-priests learn to manipulate their energy in ways that confound other casters. An ur-priest of 6th level or higher can temporarily sacrifice two (or more) lower-level spell slots and use those slots to prepare a higher-level spell. The higher-level spell must be of a level the ur-priest can cast. Only one exchange of this sort can be made each day. The levels of the lower-level slots are totaled, then reduced to three-quarters (round down) to determine the level of the extra higher-level spell slot. For example, an ur-priest who sacrifices a 3rd-level spell and a 5th-level spell can use that spell slot to prepare an additional 6th-level spell (3 + 5 = 8, and 8 * 3/4 = 6).
