Bleed

Name	Description
Bleed	Bleed inflicts physical damage as a percentage of weapon damage over time (dot).

When bleeding the damage your Bleed will inflict on a target will display as a dark red portion on the health bar. The bright red portion is the monster's remaining health. This means that even if the monster's health (bright red portion) goes to zero the monster remains alive until the dark red portion (the bleed dot) has finished 'bleeding out'.

It appears that the monster can not be killed by any other means until it has bled out. This won't apply when using Rupture as that applies the total Bleeding damaging at once as you rip your weapon out.

The Barbarian has plenty of skills that inflict Bleed and boost it.
