Snake Shapeshifter, 4th Ed Options

[Mystweaver]

Hi everyone,

Looking for some help. Going to be starting a campaign soon but one of my players would like to be a Snake shapeshifter. Unfortunately, there are no such rules for a Snakeshifter and I am wondering if anyone else has come up with a BP cost with a list of attribute limits and powers?

General powers would be perhaps:

Enhanced Senses: Thermographic Vision, Low light Vision, Heat Sense?, Smell

Now onto specifics:

Constrictor:
Attributes as Bear?

Huge: Articulated Python (up to 8m, 150kg).
Movement base speed of 1/4 its length in m per combat turn (2m), but can strike up to 3/4 its body length away (6m)... aka reach 6???
Engulf: As Water but DV= Str/2+3. Escape with Str + Body vs same (very very difficult to escape... only trolls will stand a chance really)... which is about right.
Climbing always counts as assisted.

Pros: Amazing reach and engulf is almost impossible to break
Cons: Massively visible and slow moving. Will need skill in stealth based skills to get within strike range of target.

Medium:
TBC
