Health degeneration is the constant loss of a creature's health caused by various effects, notably conditions and hexes. All effects that cause health degeneration stack and are negated 1:1 by health regeneration. If the total degeneration is stronger than total health regeneration, it is represented by left-facing pips on the health bar; each pip represents a loss of two health per second. The maximum degeneration is capped at 10 pips (i.e. a net loss of 20 health per second).
Four of the ten conditions cause health degeneration.
A health bar under degeneration from bleeding
A health bar under degeneration from a hex
The descriptions of the majority of skills causing health degeneration use the double negative phrasing of –[n] health degeneration
rather than the more technically correct, –[n] health regeneration
