Made the edits.

Brought down Tessa's stats so they aren't borderline god-tier.
Removed all indication of psychic power and rather made it just a power that is difficult to restrain.
Switched the metal in Tessa's wrist claws from titanium to folded steel, similar to that of a katana.
Changed the .45 caliber pistol to an auto loading hand crossbow.
Changed Tessa's fail safes to remove the chloroform and the stun gun, opting out for just anesthetic drugs of varying type. Alternatively, one could just whack Tessa over the head to knock her out.
