Disruptive Cleave (Wyrdsunder)

When you hit a creature that can cast spells with Wyrdsunder, you can trigger Disruptive Cleave. The target must succeed on a DC 17 Constitution saving throw or be silenced until the start of your next turn (unable to cast spells requiring verbal components and unable to speak).

Note: Use this immediately after a confirmed hit. D&D Beyond cannot auto-apply the silence condition — have the DM resolve the save and apply the condition.
Requires attunement to Wyrdsunder.
