A Slay is a powerful attack which does 50 points of damage. Nothing besides Slay stacking, described below, may change this number. Slay cannot be combined with other skills or abilities. To use a Slay, the attacker must declare “You are not prepared!” and strike their opponent. Upon a successful hit, call “50 Slay!” A Slay is not used up if it is avoided in any way, so the defending player must declare “Slay Hit” if the strike hit successfully. The attacker must call “Active Slay” for every subsequent swing. The Slay remains active for a maximum of 1 minute, or until used. This skill is considered used if it hits a shield being wielded or if it is Parried, but the target will take no damage.

So, there's been some back and forth about whether or not the "You are not prepared" aspect of the skill slay (or decap) is IG or OOG. I'm mostly interested in whether or not silencing somebody prevents this skill from being used, as if it's an IG call to activate the skill then silencing would prevent that.

Cheers!
