Consider bleeding as a blade crit

[Lambosaurus]

Bleeding is a great thing for PC's to be inflicted with, as they then need to treat it. Perhaps its 1d4 damage at the start of your turn? Perhaps non stacking - would be too much of a hassle to manage?

What to do if downed while bleeding? Perhaps it cannot inflict additional wounds? Is is even a good feat? Probably better to guarantee kills rather than inflict dots.

Is there an alternative?

I can definitely see it being more valuable against large armored foes, but less valuable against pathetic little goblins. Maybe make it stack, so we don't have to roll each turn, and instead add stacks based on the number of dice rolled. So 2d6 on a crit would add 2 stacks, causing 2 damage each turn, 2d6 + 2d4 would give 4 stacks or 4 damage each turn.

Perhaps if you simply get 3pts bleed per round per crit you spend? This way you can just have stacks of bleed being a smaller number. And this way you can spend lots of crits to get a lot of bleed. This way its more inline with other status effects.
