Likely the OAT>this but OAT is much lower base dmg, higher delay and I dont know the OAT% but if anything like Joyeuse it doesnt stack with DA gear/JAs at full potency. so likley there isn't much in it. Given DRGs multi hit WS a 4hit 126dmg or 5hits with 100 dmg comes to about the same
I have the lvl 85 of this I don't plan on taking it any further. It makes for an easy 5hit /sam though. I need to make oat or fake emp, because I refuse to collect 100 chloris buds lol.
