LSJ - Concoction of Vitality issue

Hi there. If my minion has a Concoction of Vitality equipped: [i]Concoction of Vitality, Equipment, 1 pool Unique equipment. When the vampire with this card announces an action, he or she may burn this card to prevent vampires from blocking that action. If he or she does so, this vampire cannot play cards requiring Disciplines until the action is complete.[/i] and I want to play with him a Govern at inferior dominate ( D: Bleed at +2 Bleed) Can I burn the Concoction as I announce that I play a Govern, to make it unblockable by vampires? Of course, after burning it, I won't play discipline cards. Thanks

[ quoted text not captured ] Thats perfectly right. Order is you play govern, then as you declare that action, you activate the concoction.

Thanks to both of you, Blooded Sand, LSJ :)
