Cloud Serpent (W) deals a bit of damage and heals over time. Blinding Wind (E) is the ability that blinds enemies
there is a talent that causes serpent to launch a wind when applied, but personally i consider that a wind talent, not a serpent talent. it has no synergy with any of the other serpent talents
(& i’ve always really enjoyed building around serpent, but it received nerfs some months ago and just doesn’t feel as strong as brew or wind builds anymore 
)
