I play archer since beginning (2,5y) and i always thought its a class/character thing, but today i found out by coincidence, its not.

The green dust doesnt disapear by detach the mainhand weapon, but as soon i relog or switch character and switch back, it disapears. I think it is on the weapon, because as soon i equip the mainhand, the green dust is visible again.

and i think the green dust should disapear by detach the weapon, thats why i decided to post in the bug topic.

I believe it's associated with the "Breath of the Spirit" skill, and defaults to "Breath: Recover", which has a green effect.  "Breath: Deceleration" has a yellow effect, while "Breath: Stun" has a white effect.

Use Breath of the Spirit,  select the effect, then use Exhale or Steady Breath to use the effect.

Well i just hope it should be meant to be invisble as soon main hand is off, as that effect is annoying when it comes to do screenshots.... Of course i could detach mainhand weapon and relog character for get rid off the effect, but damn for every screenshot? And of course i could use another class at all, but my archer gots the most outfits and i dont play the class just to run away when it is about doing screenshots. Even when i zoom in that the char gets invisible, the green dust is visible almost always and even then .....
