Been on a search for various uses of Greater/Bestow Curse and have made a list of the various uses printed by WotC both in printed books and a Dragon Magazine (makes me wonder if there are more floating around).
So with that I updated the Curse ability with the list of Curses for those people that don't have the source material yesterday but work kept me from bumping the post.
Seems that nobody has any complaints as of yet, but I'm still looking for more critics if people are willing to give them out.
Edit:
That's and interesting idea, sadly I haven't delved into Race creation Homebrew as of yet.
