PC on a Vampiric Storm Bow of Fortitude

I was wondering how much this storm bow would be worth?

15-28 dmg req. 10 marks
+15% while hexed
+5 Health per hit
-1 Health regen
+30 Health

Anyone know?

I hope you didnt mod it... i think it could be worth around 50k for the right buyer... waiting for more opinions

thats how it came out of the chest, I didn't mod it at all

So it was a very lucky drop gratz ^^
