What kind of actions do not require prime for immortals?
What I am trying to ask is to what extent can an immortal do something without spending any prime point. With every immortal has different bodies. With physics affecting the world in a similar fashion, would a large immortal be able to exert more strength than a small immortal? Or does the size not really matter for immortals? Also some immortals are beings of fire so for them, without even using any prime, they could start burning things. How will that work?
