Remember that stats scale as you level up. At level 24 this thing is godly but at level 50 it is EVEN MORE godly. Attack speed scales your damage harder than anything else later, coupled with huge Vit and dex, this thing is amazing.
For instance, at level 48 you get 23 HP per vit and about 3 damage per dex. As well 9 damage per 1% of IAS, which scales more as your damage goes up.
So at my level this would add about 1650 HP and 330 damage. Which is huge from one piece.
Good luck man.
