Guild Wars 2

It reduces the duration of conditions applied while the effect is active. That means if you have conditions on you, they stay at their current duration, and if someone has condition duration modifiers, say to 150% duration, the conditions applied while it is active will last for 150-100% duration, and end up lasting 50% of their base time.

Berserker’s Stance: Increased the recharge to 60 seconds. Reduced the duration to 4 seconds. This stance now reduces incoming condition duration by 100%, so only modified conditions can get through.

it states “incoming conditions” which would imply conditions that are applied while in the stance. seems to be intended that way.

bwahh alright thanks, don’t mind me
