Linked Spell (Feat)
You are able to make your magics resonate through your magical skill, so that creatures affected resist or succumb together.
Prerequisites: Caster Level 16, Coaxing Spell (Feat)
Benefit: A linked spell must allow a saving throw. A spell cast as a linked spell that affects at least two targets resonates internally as it is cast and sent forth. If any creature affected fails their save, then the caster may choose one other creature in the effect who succeeded on their saving throw and force them to use the same save as one of the failed saving throws. The caster must choose which failed save to apply to the specific target they wish. If the new result causes that creature to fail their save, then they are fully affected by the spell.
If all affected creatures succeed or fail on their saves, then this feat has no effect.
Level Increase: +3 (A linked spell uses up a spell slot three levels higher than the spell's actual level.)
