Guild Wars 2

Just messing around with builds, thinking about building a might sharing build using the grandmaster tactics trait, for random groups with guildies where not everyone is zerker (got too many armour sets and trying to think of uniqueish builds for the non-zerker sets to run with), and I can single handedly give the whole party massive might stacks, anyway the empowered trait says:

Increases damage for every boon on you. (1%)

Does anyone know if this is every unique boon? Or, for example, would I gain 1% for every individual might in the stack? This seems unlikely but I would like to ask.

It’s for every unique boon you have. So 25 stacks of might gives you 1% extra damage.

Ok thanks, theorycrafting while bored at work so couldn’t fire up GW2 and test it (not sure how I would anyway). Useful trait but not as powerful as it could have been I suppose.
