As two actions, you speak a word of power that causes waves of intense pain to assail a creature that isn’t a construct or an undead that you can touch or see within 10 meters which must make a Fortitude saving throw.

On a failure, the creature is subject to crippling pain for the duration. While the target is affected by crippling pain, any speed it has can be no more than 2 meters and the target also has disadvantage on skill checks and saving throws, other than Fortitude saving throws. Finally, if the target tries to cast a spell, it must first succeed on a Will saving throw, or the casting fails and the spell is wasted.

A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Augment

You can target one additional creature for each additional mana expended. The creatures must be within 5 meters of each other when you target them.
