Back home now, came to a shit show so let's be real.

30 damage over 2-3 turns is incredibly useful in PVP. It stops Ghosts from Last-Chancing your ass and surviving if you're slower (assuming the lightning smacks them to get them into that range). The poison also can afflict and synergize well with Hexer if you can't afflict someone, giving more DoT effectiveness to it.

It's also a 7 star, meaning it can mutate into a bow (which is a lot better in the upcoming update). Not to mention that it synergizes well with evokers, or really anyone, who wants to zap a bitch and stab em at the same time. A lot of weapons don't have 'PVE' potential. Here are some other 7* weapons.

The Entire Magical Series
Vampire Bat
Magnifying Glass
Konosekai
Mugendai
Whulf
Yin/Yang
Deadly Smile
Yukijin
andd the Rose Whip

Most, if not all of these 10 stars are GOD AWFUL at PvE. The Mugendai and magical series being the exception due to great scaling and weapon effects.
