Ok, I've updated the Seeker.
Droped skill points to 4, added the 6th level power Inspire Music (realy mostly a flavor thing, I almost could give it at first and it wouldn't be that bad), adjusted the spellcasting, so now they use their own spell list but increase on the bard casting.
I also tweeked the Level 0, 1 and 2 spell lists. Comments and suggestions before I continue would be greatly appreciated.
