Guild Wars 2

Currently its 30 seconds but the tooltip is confusing.

It also only works when you have warhorn equipped.

I have no idea what the 10 could be referring to.
Something is in error, but it’s unclear what.

There is currently a known bug that causes the cooldown of imbued melodies to be 30 secs, or 20 with Geomancer’s Training, which is the same cooldown as sandsquall. Also, the tooltip does not specify this, (maybe a bug?) but you have to have a warhorn equipped to cast sandsquall from this trait.

I hope this helps.

So its intended to be 10 seconds?

Wish it would get fixed so I could make use of a pretty great trait in that case.

The 10 seconds is a relic of the old trait. (Notice how badly rushed Tempest was.)

Old trait was 10 sec ICD for a breakstun on allies when using a warhorn ability. Which no longer exists, thankfully.
