Wish Points System

(Si)Sasuke gains a "Wish Points" every year. Yue essentially crystallized my hopes and dreams, forming them inside her body and then consumes said hopes and dreams.

The things that mater for cost are "scale" and "weight"

The more people it'll effect, the more it costs.

The bigger changes to the "natural order" of the world, the more it costs.

So something like changing my eye colour would be really cheap. Something like changing everyone's eye color would be more expensive.

But changing my Sharingan so that no one notices it costs more than that, because "naturally" that's one of the Sharingan's weaknesses.

Esentially, the further my wish goes from Canon, the more it costs.

Examples:

Change How Mangekyo is activated - (5-10~ points)

Remove Mangekyo downsides (10~20) points

Make myself a Genius (15-20~) points

Change Hair Color (1 Point)

Summon a Car! (7 Points)

Grow wings! (6 Points)

Become A Tailed Beast! (40-100 points?)

Gain like a sage of 6 path mode or something? (40-100 Points)
