well if i use it it works- i tested it in the Arena Stage3 foundry - 500zombies in 2 small rooms , gooing in with daily and after 5s i got dmg so it works
why are u skilling deep gash? okay it sounds nice 15% of your total power as bleed dmg - with 4100power it ticks with ~110 its nothing the tooltip is totaly wrong : 4100/100=41*15=615 d,g/sec if you believe the tooltip
