Seal of Command SHOULD:
do 2x damage on crit
Never: miss, parry, be blocked or dodged, it should have its hit calculated based on melee hit, however when missing say resist instead of miss
have a 1 second internal Cooldown so it cant proc more then once off attack multipliers such as hoj or reckoning
have a 0.5 Second delay following white damage to allow for vengeance effects.
