*****************************
As I want to create a story with fewer plotholes necessary foundation has to be laid. Plausibility is a form of currency in the world of Arcadia that has many uses one of which is purchasing and upgrading skills.
*****************************
From now on I will call Plausibility 'P' as an abbreviation eg- 1000 P
*****************************
So this is the price for purchasing a skill based on their ranks
G-RANK- 25 P
F-RANK- 50 P
E-RANK- 100 P
D-RANK- 200 P
C-RANK- 400 P
B-RANK- 800 P
A-RANK- 1600 P
S-RANK- 3200 P
SS-RANK- 6400 P
SSS-RANK- 12800 P
*****************************
So this is the price for Upgrading a skill based on their ranks
G-RANK To F-RANK- 25 P
F-RANK To E-RANK- 50 P
E-RANK To D-RANK- 100 P
D-RANK To C-RANK- 200 P
C-RANK To B-RANK- 400 P
B-RANK To A-RANK- 800 P
A-RANK To S-RANK- 1600 P
S-RANK To SS-RANK- 3200 P
SS-RANK To SSS-RANK- 6400 P
So the total upgrade cost of a G-Rank skill to an SSS-Rank Skill is 12775 P
