Guild Wars 2

Yes. However + condition duration and – condition duration cancel each other out. So if you have -100% condition duration and a necro has +100% condition duration, the duration increase and decrease will be added together before the final duration is calculated.

Hi my question is, if the percentil from duration decrease have a cap?
for example a DPS Warrior with Melandru/Hoelbrak Runes+ Lemongrass+ soft cc reduction from trait
= 98%/93% + Guardians fire field = -131%/126%, that means this war is imun against soft cc in this situation, or is there any decreasecap?

sry my english is bad

Melandru Runes+Lemongrass+Dogged March give -98% on Cripple/Immo/Chill duration but only -65% on all other Condis. With Purging Flames you get up to -98% duration for all condis and theoretically 131% on soft cc but i would guess that -condi duration is capped at 100% as well.

No the resulting durations are capped at -100% or +100%, but that is after +duration and -duration are added together. So If someone has +100% duration and you have -130% duration, the resulting duration would be -30%.
