Changeling Abilities, Natural Poison - Internal Release Options

[The Jopp]

Ok, this was a concept i was working on and off with and I started to wonder about the feasability. There are several themes of this character in movies and stories and there are drawbacks.

Lady Poison

Changeling III
Natural Venom [Ekyelebenie Venom] Interna Release
Retractable Claws
Defensive Secretion (can deliver poison?)

NOTE: Eyekebelenie venom can EASILY blind most targets and has a contact vector and a strength of 8. You need a 5 point quality to be able to have availability to the poison so we can say that this ability cost 15 points (I cannot see that you would get ANY poison above availability 12 regardless what the ability says without Restricted Gear quality.)

Normally Internal Release wouldnt be working by RAW as the rules say Spat or Exhalation but as the character has COMPLETE immunity to the venom i dont see why it couldnt float around in his/her body.

Pros:
Can kill with a kiss
A sweaty palm can be used to poison someone
Blood and other bodily fluids would be dangerous to anyone attacking her (Surprised vampire/ghoul)
Retractable claws would also be coated with the poison
Team can use character as a font of poison...
Implanted dartgun can be filled with bodily fluid as poison

Cons:
Can accidentally PERMANENTLY blind anyone
Can accidentally KILL anyone
Leftover bodily fluids can poison/kill people
Docwagon could deny her service (manages to blind doctors/nurses/surgeons as they work to save her life.
Teammates might be reluctant to help her if she needs medical help
A DNA profile can be rather easy to create after a short while.

Unbalanced? Dangerous to play? Fun?
