When Earthiverse made their changes to the skill system, they inadvertently change a piece of the code that made it so that when a skill was attempted to be used on cooldown, the response would be sent with `place: "skill"`, and the result would be a hung promise, as the client is waiting for a `place: "curse"`, or some other `place` value, depending on the skill they used.
This PR makes Charm more consistent with the other abilities, and actually consistent with the item description. Also adds a dedicated description for the Charm ability.
