New Class: Stealth Assassin

[Poizenous]

I think it would be cool if there were new classes made like assassins. Now, what I was thinking assassins use as weapons are two blades. You can put one in the shield slot and one in the weapon slot. And u can do moves like:
Invisibility-lets you become invisible for 5 seconds so u can sneak attack on a monster or person.
Double slash- hit opponent two times really quickly
Quadruple slash-hits opponent 4 times quickly
Adrenaline stealth- increases strength and speed for a certain amount of time.
Poison jab- hits an opponent draining their health for an amount of time.
Back stab- flashes behind a person quickly and stabs them doing a critical amOunt of damage.
Meditate(passive)- stands still for more then 10 seconds and heals double the Mount it health while walking
Blood drain shot- uses ur own health to make a deadly Strike
Crystal healing- drains health to make crystals.

Tell me what u guys think about an assassin class!
