From Arcanet
This spell joins the bodies of two targets. It's range of application is immense as targets can be fused in almost any configuration and to almost any degree. Two bodies could be fused right down the middle such that both are fully functional and capable just as much as one could be fused to a specific part, or functional part, or another's body. Though this cannot change the particular shape of one of the targets, i.e. it could not be used to transform one target into another's cock, it could conjoin their bodies in such a way that one's muzzle or mouth essentially ends up a "sheath" for the other's cock. Parts of targets' bodies which are entirely immersed within the other's simply cease to be.
