Your unarmed attack damage increases as you gain levels, as noted on the Vowed table.
You may add your Punch skill to the damage done by these attacks as usual, but Foci such as Unarmed Combatant that replace or improve your usual Punch damage do not apply to you.
As a Main Action, commit Effort for the day to transform into an available alternate form.
This shift persists until you die, shift to a new form, or end the transformation (as an On Turn action).
Your hit points, System Strain, and other scores remain the same in any new form, but in a non-humanoid form your class’ base attack bonus can be no worse than the one listed on the Skinshifter table.
If your shape is quadrupedal, its Move is 10’ faster than your base.
Your Form’s shape improves your Charisma modifier by +1, to a maximum of +2.
There is always something alien about this beauty, and such forms can never be mistaken for an entirely normal human or animal, though they may be taken for some exotic demihuman or altered baseline.
