First of all, i like the concept of the class, but not the way it is excecuted. So, there i am whit some ideas for a rework, if you would like to apply those. Had a pretty lot of fun playing this class, and i got some kind of affection to it... So, lets start:

Base stats:
HP: 10/14/18/22/24
Dodge: 5/6/7/8/9/10
SPD: 3/3/4/4/5
DMG: 1-4/2-6/3-8/4-10/5-12
Crit: 4/5/6/6/7%
Acc: 2/4/6/8/10
Prot: 0% (all ranks)

Critical buff: +10% stun and debuff chance.

As a squishy one, he dont feature a lot of tankiness. His most strong points reside on his big amount of acurracy, decent dodge and speed.

Resistances (base):
Stun: 75%
Bleed: 45%
Blight: 45%
Disease: 70%
Move: 10%
Debuff: 55%
Trap: 20%
Deathblow: 50%

Skillset: For his skills, he relies more on confusion, disruption and some other dirty tricks to survive. As a fragile being, he needs constant protection to survive, who he easly found, between his allies and enemies, no matter if they want or not... Even his allies may found strenght on his mental tricks, but having someone driving you mind its not exactly a healthy process...
