PC on r10 warhammer, unconditional +15%

Yeah, just bought an unid gold and ended up getting a r10 war hammer with an unconditional +15% midmod. I've heard they're rare, but haven't been playing GW long enough to know for myself; anyhow, was just wondering if anyone knows what this might be worth. Thanks in advance to anyone who answers

Is it 15% -5 energy, -1 energy, or -1 health? Post a picture if you can.


Edit your post to add info.

well, the stats bar for the weapon said (word for word)

War Hammer of Defense
Blunt Dmg: 19-35 (Requires 10 Hammer Mastery)
Damage +15%
Armor +5
Two-Handed
Value: 316 gold

but then strangely after I posted on guru (and told the dude who sold it to me), it changed from an unconditional to 15^50. IDK if I am seeing things or am just crazy, but I could have sworn it was unconditional. *Awaits flames for wasting peoples time...*
Sorry >.>
