Guild Wars 2

Does anyone know how these stack?

Geomancer’s freedom is -33% duration

Then there’s Melandru or Hoelbrak runes for -20 or -25% duration

Then there’s -40% condition duration food.

Is it possible to get -98% duration on immob, chill and cripple? Or do those conditions end up being (.666*.6*.75) only ~30% of original duration?

Seeing as how boon duration buffs stack, there’s little reason why these wouldn’t. As for the exact numbers, the best way would probably be by testing it. Isn’t there an NPC in the PvP area that causes conditions? Maybe the engineer and immobilize?
