Heat Sync [Warhorn 4 skill] how does it work?

I tried to test it today to see how i can spread my boons. I did it with a wvw keep guard.

At first, i built my boons up. I had protection vigor regen and swiftness.I tried using Heat Sync but I saw that the guard only got some might from the skill effect with no other boons.

Anyone can explain how to use it properly to me ?

Heat Sync copies Might and Fury 'only' before spreading these two boons to 10 allies, it doesn't work on other boons. Upon sharing these two boons, you spread the same Might stacks on you as well as Fury duration

It applies 3 stacks of might on you, then it applies a copy of all your stacks of might and fury over to 9 other people. The copied boons are not extended by boon duration.

thanks for the explanation. I thought it applies all of the boons i have.

That was the idea originally but they decided to give that to signet of inspiration instead because mesmers were underplayed at the time.
