Guild Wars 2

Hey, I was wondering if Quickness (the buff that makes your attacks twice as fast) stacks in duration similar to how boons and conditions do.

For example, if my weapon rune procs me Quickness and I pop Quickening Zephyr will they both stack together or will I lose out on one of them.

Thanks

Stacks duration. ie. it lasts longer as if you used the other right after the first.
