Video: https://www.youtube.com/watch?v=eTsQImRB75Q (notice that i don't have any venom or dot effect in the video, the dmg u see is mele dmg (Hoja de las sombras = http://www.db.pandawow.me?spell=121471/shadow-blades, Golpe = http://www.db.pandawow.me?spell=6603/auto-attack)
you can test it with shuriken + http://www.db.pandawow.me?spell=121471/shadow-blades talent also, the bug is more obvious with that.
