You place a curse upon a target character.
The target has their Ritual Fatigue and Aether Channeling attributes reduced to 0, and those attributes cannot be increased above 0 by any means. The target cannot contribute Ritual Power to a ritual via any method.
The effects of this ritual last until the end of the next event, until you choose to remove it, or until the curse is broken.
Roleplaying Effects
The target finds it difficult to speak. They can still make noise and communicate, but feel like they’re constantly on the verge of forgetting how to form the words they want to use. This can manifest as a stutter, a tendency to trail off mid-sentence, or just using as few words to communicate as possible, depending on the target and how they respond to the curse’s effects on their ability to use language.
