Phantom Speaker - Action Modifier

Only usable if this vampire is blocked, before block resolution.
[chi] Cancel the block resolution (the action is still blocked).
[mel] Not usable if the blocking minion is an older vampire. The block fails, and the action continues. The blocking minion cannot attempt to block this action again.
[MEL] As [mel] above, and if this action is successful, lock the blocking minion after action resolution.
