Upgrade Soma

Upgrading of Somas can be done by using items called Rimae and talking to Rapper Rapper located in White Aurora Base beside Luna's Room.

By talking to Rapper Rapper, one can "absorb" a stat from one soma, and "strengthen" another soma.

Example: Soma A has +320 HP while Soma B has +560 HP Having a Rimae at hand and talking to Rapper Rapper, I remove the +320 HP from Soma A (thus changing the form of the Rimae) Next, I strengthen Soma B with the Rimae that has the +320 HP stat. What comes after is completely random as of now. It may however:

a.) Succeed and transfers the whole amount. (320 + 560 = 880 HP)

b.) Succeed and transfers only a % of the amount (160 + 560 = 720 HP)

c.) Fail and do nothing.

d.) Fail and lower the stat of the Soma you are trying to strengthen (560 changed to 380 HP)

However, there are limitations to Upgrading Soma:

1.) A person cannot, I repeat, CANNOT upgrade Native Items.

2.) Somas and items have only 10 chances to strengthen. (meaning if 1 failed, you'll only have 9 more times to try to upgrade the soma)
