+15%/-1 Chaos Axe

Hey guys, found this today:
Q9 Chaos Axe
inherent +15%/-1 health
furious 10%
hp + 29

Saw someone selling something like this r8 for 35e, so was hoping it would be worth a bit

Thanks in advance

is the -1 health or energy?

15/-1 health is very nice, i would say around 90-100k, but not completely sure, get more opinions
