The proposed change corrects the cost. It also ties Shapeshifting back to Sorcery, as it is in the Courts of Chaos. How does this sound?
Advanced Shape Shifting 65 Points (Basic + 30)
Shape Shift Aura, 5 Points, alter your mystic Aura at whim, also what your mind feels like to external mental touch. (Because getting mental impressions is important for things like Trump and Logrus and Shapeshift Persona, this is left as is.)
The following are updates to the corresponding lower level powers. As such they remove the concentration aspect. Although they do require sufficient psyche to keep your personality separate from what you are mimicking.
Shape Shift Features, 5 points, Mimic another physical appearance, can be done piecemeal, doesn’t require concentration.
Shape Shift Persona, 10 Points, (Shape Shift Feature + 5 points), mimic another’s personality.
Shape Shift Internal Structures, 5 points, add an extra heart or other organ, or move your own. You may also regenerate now.
In order to shapeshift into a form that uses a power you need to have an appropriate level of Sorcery, Conjuration or Power Words. In addition, you must have designed an appropriate spell / ritural using Theory or have a psychic impression of a creature that can do so. Because these are based on Shapeshifting, they are harder to dispel and are based on your endurance instead of psyche.
- Internalize Simple Power: (5 Points) Replaces Animal Abilities. In addition, with Basic Conjuration, you can alter your mass when you shapeshift. Shadow Shape or Empowerment allows you to gain armor or other simple physical and internal abilities. (Such as resistance to fire, the ability to breathe methane, hibernation, or razor-sharp retractable claws.)
- Externalize Simple Power: (5 Points) Similar to Creatures of Power, you may develop simple offensive abilities. Dragon's Breath, frost auras, electric eel bioshocks, and other simple, physical powers. you may also summon basic creatures of blood (purely physical creatures). This requires an appropriate spell, although it need not be identical. So, even something like Power Word: Spark (Aflak!) could be used to create fire breath.
- Shift Complex Power: (5 Points, must have BOTH previous powers.) No longer bound by the simple powers, your ability to change mass is limited only by your endurance. You can create complex magic effects such as a medusa's gaze, wingless flight, or the ability to travel through Shadow. You may attempt to shapeshift others by touch (either through transformative poison or a mutation-based aura. Remember, this is now Endurance vs Endurance). Creatures of Blood may have other powers, such as Shadow Seeking, and can be built with the creature rules (as if you were conjuring the creature normally).
Shape Shift to Animal Abilities, 15 points, (Persona + 5), mimic part of an animal’s ability, without becoming that animal. This includes instincts of how to use the abilities.
Shape Shift to Creatures of Power, 20 points, (Animal Abilities + 5) mimic fantastic creatures, even those that can shift through shadow.
Shape Shift Blood, 10 points, (Internal Structures + 5), This is the start of being able to split parts of your body off as independent beings. You must have Shape Shift to Creatures of Power if you want to imbue your blood with any abilities.
Shape Shift Others, 5 Points, by touch. This requires you defeat them in Psyche.
