Zrael (Aligned Form Hints)
From LSWiki
Zrael is one of the best Aligned forms to have in my opinion.
It summons Zrael herself, and allows you to learn some of her knowledge.
To summon her, you must her have a piece of her remains, such as a bone or ... rod ;)
To learn the form, you will need to do almost every quest possible. But, you get points for having Zrael IDed
