Okay, so I thought of an idea for Chakra and Stamina usage for jutsu.
There will be a slight difference for some of them, as you can easily tell on Bloodline Jutsu such as Oversoul's and mine.
For some of the jutsu, there will be normal usage. Ex: 45(CP) 45(SP)
While some might be more costy, meaning they will drain by percentage. Ex: 50%(CP)
So lets make up a jutsu here, say it drains 45 CP. The user has 100 CP.
Now, after using the jutsu, the user's CP is decreased by 45. So a total of 55 CP will be left.
Now, for percentage. let's say the user has 200 CP. and the jutsu takes 50% down.
What will be left? Decrease the CP by half. Which means 100 CP will be left.
___
Now let's combine them. Let's say the jutsu takes down 45 CP and 50% SP
the user has 200 CP 200 SP
what will be left? 155 CP and 100 SP.

NOTE: There will be times where some jutsu will decrease health as well. Such as Rinnie's Bloodline jutsu. Just do the same for the HP as you would do with CP/SP. If it says 50% HP, the user loses half their health. If it says 50 HP, the user loses 50 health points and thats it.
