If neutrals could have their own unique things to conjure that were not dependent on alignment. The Djinn idea would be interesting to play out.

And nerf oposite alignment conjurations for the other two alignments.(Goodies could not conjure nightgaunts, demons, devils) Goodies would gain some new goodie only spell to compensate for losing nightguants. These changes would be almost akin to having three new classes. A bit of tweaking to other spells, and sculpting to the alignment of each group, and you could have three completely diferent conjuration classes.

What do you think Zhulg?
