Training

[Sol]

I didn't see a staff only tag so I just figured I'd jump in, hope nobody minds...but just so you know Spiritken is only learnable by humans/non-transformers, Piccolo would be a namekian and thus unable to learn it.

You'd want:

Super Namekian (SNS)- Unlike the similar transformation of the Saiya-jin race, the Nameks ascend into their enhanced form with greater ease, requiring no emotional trauma, but rather focused intense training on their home planet. As a result of the control that they have over when they ascend, and their method of training, their physical structure must be slightly more powerful than that of the other races.
Requirements: 1,200,000 Ki, 270 Determination, Two Weeks Training on Namek-sei.
Multiplier: x20 Ki
Species: Namekian

EDIT: Hope that helps, if not...sorry for the intrusion.
