Void Knight Portal Training: Void Knights can make a magic check DC 15 on a hostile portal to make it attackable. Getting 30 or above instantly abolishes the portal. Likewise, they can make a magic check DC 15 to start summoning a portal, taking 1 minute. DC 30 instantly summons a portal. Both of these abilities share a cool-down of once per day per 4 character levels.
Bloodmarked: Being marked by Vampyres, your blood is scentless to them. Any attempts to sniff you out by blood takes a -20 penalty.
