well pathfinder limits 1 level dip prestige classes to +1 will, I assume you need the base will for words of creation? How about Paladin? +2 will base in pathfinder. Can then add a second level and enjoy your cha to saves, not quite sure where you're going with the build. Wouldn't it be more powerful to just go bard 1 crusader 19 with song of the white raven and just wait for words?
