So firstly this is a very strange situation. Mad dog essentially spammed a bunch of OPEN/PvP threads and was killed in several of them if I'm not mistaken on that series of suicide runs. With multiple factors in mind this counts as only 1 PvP Win. You are approved for the Crycoaster and Vambraces. The 2 pvp reward for the XS-109 is denied as is the Slayer Sigil. I advise that you do not go into multiple PvP threads with the same enemy in the same span of time and expect to get rewards out of them for future reference.
