I actually tried to use the tome i bought from the camp site merchant but couldn't use it with morrigan, then i read on some faqs that tome of skill is only for the warden, i'll check out the tomes from other stores. Thanks for all the advice.

I'm on my second run with origins since i can't wait for DA2, i wanted to know if there was any way to quick upgrade the skill of morrigan? I need master of herbalism but i'm quite far from leveling up. I tried using the tome of skill of sundry but it's only for the main character? Is there any other way? Thanks.
