Condition Duration

 Condition Duration, also known as Expertise, is a secondary attribute that improves the duration of all conditions inflicted by the character.

Duration of conditions is rounded to nearest quarter of a second in skill tooltip's list of effects (0s, ¼, ½, ¾ and 1s) and conditions which inflict damage over time (bleeding, burning and poison) only deal damage each full second. Condition duration from runes isn't shown in the skill's tooltip, but does correctly increase duration.

Trivia

• The diamond-shaped icon for this attribute (and for Condition Damage) is a relic of early development, when all conditions had diamond-shaped icons in different colors, instead of the uniform red icons they have now.
