Beejallyla's Creature Splice
Magic-User Spell Level 4
Beejallyla's Creature Splice combines any two different types of creatures with total hit dice equal to or less than the caster's hit dice. The referee determines the result of the splice—the monster's intelligence, temperament, abilities, fusion of physical traits, etc.
The new creature has a 3 in 6 chance to survive the combination. Creatures that do not survive have a 1 in 6 chance to rise as undead on the next moonless night.
