Guild Wars 2

On a rune set if the 4th item says “25% chance when hit to gain might for 10 sec” does things like boon duration effect those? So let’s say I have 40% extra might duration and 10% to all boon duration, when that 4th item on my rune procs will I get 10sec might or 15sec?

I don’t see why not! It should work unless there is some fine print involved..

Yes it affect it, but it won’t show up on the rune. So the rune will alway say 10sec of might, but in that case you will actually gain 14sec.

^ what he said. the runs will never show updated skill fact info, but their effects are affected by your duration increases. you can see this with condition duration increases if you hover over the stat on the hero menu. it will show you which conditions are boosted beyond the global listed amount. iirc the same cannot be displayed for boons, but you are still getting the benefits.

As long as a rune procs an actual boon to affect, it will be affected by boon duration. Same goes for conditions and condition duration.
