Ritual of Twaining

Lost spell. A complex and arcane spell of 4th level, used in magical cross-breeding of dissimilar natural species; creating, for example, a rabbit-lion, an owl-bear, or some similar creature.

A recommended substitute is to treat this ritual as a prerequisite to breeding a specific combination. The processes required to produce the combination are discovered through the spell research system (the ritual of twaining rabbit and lion being the equivalent of a 4th- level spell in terms of time and monetary cost).

The DM has the final say over what combinations are possible or viable once created; the wizard in this case is merely studying a promising lead.

For example, a rabbit-lion might be white, furry, and herbivorous, with 4 limbs, a mane, a quivery nose, long ears, big canine teeth, and a manic depressive disposition. Such a "successful" crossbreed might well die off in the wild.
