mana burn on Dragon Slayer

Recently i made an augment to my DS. It gave me pd +18 and a randomly mana burn skill. I wonder how useful it is on PvE or PvP.
I've seen it working on mobs but i'm not sure yet how much damage it causes or if it's useful or useless. Anyone has a clue?

Damage = 0
PvE = mob is dead before you have managed to drain all the MP from it.

PvP = no idea, but I would guess the effect is minimum.

Well, since you are a fighter, your cast speed is probably slow enough that it really wont be worth it, but I could be wrong.

please post a screenshot, is it an active skill? a passive chance on strike? passive chance when someone crits you?

It's a passive chance on strike, not an active skill

crap imo.

Yep thought so, useless. And it was a top ls.

My DragonSlayer augment is a chance to root anything that hits me(magic, archer, melee, if it does damage, it has a chance to get rooted). It's rather nice(although I wish it would fire a bit more). Got it from a regular lvl 67 LS.

That could be real nice when you're about to frenzy.

I gots me a nice augment on my DHA. VR active self buff. It stacks with VR from CH/SE/WC and lasts for about 2 mins. I think I used a MG 76 stone.

That's a super augment. I thing it has to do more the level of the the stone than if its mid high or top one. Mine was a top one, it gave nice thunders on my sword but nothing else usefull. :p

passive clarity on a bassalt hammer from a regular lvl 70 stone here :p

haha I just got active clarity on my hom for my prophet. I <3 it.

I want vr passive augment with +crit rate...then it would be the perfect weapon
