Critique my Level 7 Solo Controller : Mabine

[Kyrail]

Mabine is a primordial fey spirit of decay that has been built up a lot in my campaign recently, and I'm going to have them unexpected run into her for my first solo fight.

She is based partially on a Lamia, but heavily edited.

Do you really mean Reach...or Ranged?

 

[Kyrail]

Yeah putrefying bolt should be range 10

The other one actually is reach.
