Vow - The Judge verbally negotiates an agreement with a supernatural creature in which it promises to no longer engage in a particular activity. The Judge then traces the Judgment symbol on the creature, sealing the pact. If the creature breaks its promise, it bursts into flame. If the symbol is visible, removing it has no effect on the bargain; if the symbol is invisible, humans and other imbued can't see it, but beings with supernatural perception may get a vague sense of it. This edge can only punish a particular designated action; it can't compel a creature to actively perform an action, even if it's willing. The creature must knowingly agree beforehand, although there's nothing preventing the Judge from coercing its agreement.
