Following his defeat of Arya and emerging winner of the Civil war which he had done by getting the surviving Family heads under his thumb, Hal became privy to two Upset Victory packages from Grimoire.
According to Grimoire, his victory over Arya and other parties in the Civil war was only accounted as ONE great deed and hence warranted ONE upset victory package, however, the second was to reward him for being a big spender as of recent.
However, none of it came as an ability that Hal had to admit quite disappointed him, or at least it disappointed him until he discovered what the package he had been given were.
The first which was to reward his big-spending nature was a 100 percent discount from Grimoire to pursue a particularly expensive purchase.
However, that expensive purchase was to be picked out from a predetermined list and this saw the return of Hal's disappointment.
