SoP: Alteration -- Applying to Animal Companion
 

I can't seem to figure out a way in the Adjustments Tab or elsewhere (within the portfolio) to add the traits that can be applied via Blank Form.

Specifically, pounce, rend, & constrict


The only way I have been able to ad-hoc it is to use the Bestiary Monster Creation, and custom build the animal companion.

In the Spell Adjustments add Alteration: Shapeshift.
This will give you an Alteration Sphere tab, there you can create alternate forms you need

Where do you get "Alteration: Shapeshift". I don't seem to have that one.

It was an adjustment added via Spheres of Power, or possibly off of the Alteration handbook.

Quite a few of the Spheres of Power related abilities are coded as spell adjustments that can be picked.
