Using HXB+1 only in this pic, so.. whatever his items are, jewels/armors/weapon, I have no reason to believe the above screenshot being photoshopped or even altered in any way. The res, hp, mana.. everything seems to add up perfectly with the usage of quest jewels, now the bow he's using could be a +1 or even +3 only. There's no way of finding out if it's fake or not, unless you find out what exactly the bow is he's using.
Edit, GinzaGirl is obviously fake. Must have found a way of altering KSC' :>
