Rules Cyclopedia: Templates for variation on existing monsters

 They dont include monster templates in the Rules Cyclopedia but by comparing the normal form monster to the abnormal form we can get a creature template.

 Potential Variations include Animals (Dire, Giant) and Undead (Skeleton, Zombie).

 So applying these templates to a normal form allows us to get a considerable range of horrors.
The Minotaur (Dire, Giant, Skeleton, Zombie)

The Dire form is slightly larger (size x 1.5) while the Giant form is (size x 2).
