Guild Wars 2

I am a new GW2 player who just started at the free trial weekend. So I don’t have a character high lvl enough to test this. I’m wondering when a trait says “gain 50 precision when you use a sword”. Does it mean when you use your 2nd set of weapon which doesn’t include a sword, but your 1st set does. The bonus precision won’t apply?

The bonus will only apply when using the sword as your active weapon set. And not when you swap to your other weapon.

You can see the difference by looking at your stats page.

Even if your are low level , you can click the PvP tab from the list on top left of screen, and select to go to the heart of the mists. Here is a special area, and you will become full lvl 80 and able to test out any traits.
