Mimicry has always been a part of Dragon Ball. Goku learned the Kamehameha after just seeing it once, Vegeta and (possibly) Frieza copied the Destructo Disc, etc. That hasn't really been part of this game, though. My suggestion is to allow for basic techniques to be learned at a competent level by players writing omakes where we get them. This excludes the possibility of a cookie, of course.
Have you thought about the thing I suggested where we separate the good and evil within ourselves (but not ejecting them, so there's no change to our personality or anything), letting them crash back together, and using it to boost ourselves like the Kaioken except with a high Ki Control/Sense requirement and that uses Willpower instead of taxing the body?
Check out this picture. Only pure-blooded Saiyans have weird growth. Human-Saiyan hybrids have the same body growth pattern as humans, just as they have the same kind of hair growth. I'm mentioning this because at one point in the Quest it said that Kakara wouldn't really grow until she was 14.
If we got Kamehameha to Legendary and then used cookies to increase the skill level further, would it tip over and fire a Super Kamehameha instead?
Can we ask Berra to tell us all the techniques he knows? We're Inquisitive, he's our father, and we're 9, so curiously asking about it is both IC and not suspicious.
How does one become the Queen of Garenhuld? Is it an elective position like on Earth?
The ki produced when using Jaffur Style is described as an "almost liquid haze". If we got our Ki Control up to Elite, would we be able to make our ki
actually liquid? I'm thinking we can break it out in a fight for a quick recharge, similar to the capsules in Xenoverse.
