Displacement:
The subject of this spell appears to be about 2 feet away from its true location. The creature benefits from a 50% miss chance as if it had total concealment. Unlike actual total concealment, displacement does not prevent enemies from targeting the creature normally. True seeing reveals its true location and negates the miss chance.
Empower Spell:
Benefit: All variable, numeric effects of an empowered spell are increased by half including bonuses to those dice rolls.
Saving throws and opposed rolls are not affected, nor are spells without random variables.
The 50% miss chance is a variable numeric effect. It is not an opposed roll nor is it saving throw. Would the 50% miss chance of Displacement be increased to 75% or am I missing something?
