Was I able to?

[Broli]

From the Techniques page.

Namekian Body Size control- Only for Nameks. With this ability, you can stretch your arms to multiple times your own body length. You can even enlarge your own body, although your strength increases because you have more mass, your speed decreases a lot. Can be learned at Guru's place from Charango, one of his bodyguards.

[Sage]

Yeah... he RPed learning it, Broli. He's asking if it's acceptable that he's earned it/etc.

[Broli]

No.
