Guild Wars 2

(not fixed)Elixir X: This skill now gains a duration increase from both the Inventions trait Elite Supplies and the Alchemy trait .
i tested this in the mist and only get the buff from Elite Supplies trait not Potent Elixirs

tested in both Rifled Turret Barrels and Elite Supplies did not seem to buff the range however Rifled Turret Barrels did properly buff damage

(fixed) Freeze Grenade: This skill no longer benefits from the Explosives trait Grenadier for 5-second cooldown reduction. tested in mist works fine
