Guild Wars 2

Can someone please explain how the mich duration runes work. I have it stacked and my buffs still stay same length and the cooldown stays the same as well.

It’s sort of bugged. The might from “For Great Justice” lasts 25s. If you have a +10% might duration rune, the tooltip will still say 25s, but it will in fact last 27.5s – it works, just the tooltip does not update.

However, if you use a +10% boon duration rune instead, the tooltip does update to 27.5.
