Except as noted above, this spell is like the Banishment spell. However the material component(s) are optional, and the soulseeker gains a bonus equal to half her seeker level (round down) to overcome spell resistance and to boost the spell's DC. Also, there is no chance of sending the outsider to the wrong place, and the outsider cannot return to the Wold for a year and a day.
