Okay, so I am a bit confused. Do you absolutely need a green or yellow ability to make use of a power?
For example, say I have the cosmic energy power and have the blaster archetype. I took disabling blast and danger zone as my green abilities. I put cosmic power as my ability that powers disabling blast and say, my strength power for danger zone (like a ground slam).
Now, cosmic power is supposed to be more versatile than just an energy blast, so can I do other things with it? Can I create illusions or something related to cosmic energy? Am I only limited to the green, yellow, and red abilities? If so, that would really take away from the versatile nature of the system.
