New Cantrip or you were wondering where the Lovecraft stuff was : Voor Sign

This cantrip is consumed when used
Metamagic school, evil descriptor

You may cast this as a free action, accompanying another spell that requires a saving throw. That spell now gives a -1 on its saving throw, -2 if the target is Cthulhu Mythos related (you can substitute aberrations)
Mythos related beings will often go directly for the caster of this spell as it enrages them.
