Guild Wars 2

I was playing on my spvp thief earlier and I noticed whenever I used black powder in conjunction with heartseeker, even if I accidentally hit my opponent I would still stealth and not get the revealed debuff.

Is this intentional?

as long as you are not stealthed before hand yes thats how it should work (same way CnD works)

If you are stealthed and leap through the smoke field and hit someone it should reveal you.

If it didn’t work like that it would be a pointless combo field that would only be used by people abusing it out of combat.
