Skill Purchase and Upgrade Cost Using Plausibility - Q&A World Building

*****************************

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
