Cynic's Dissent

Cynic's Dissent allows the caster to display knowledge in opposition of an action taken by the target. The words of criticism act form runes, that wrap around parts of the creatures body acting as ropes to hold a target from success. On a failed Intelligence saving throw runes,  the targeted creature has one of its abilities, of the caster's choice, reduced by the casters Intelligence modifier until the start of your next turn.
