Basics:
LM = learning mod (average of mods for INT and WIS, rounded down)
Start:
During starting occupation you can assign the limit of the available skills up to max of 3 or 5 for specialised without a check.
To add to ranks skills:
Learning check using LM as the modifier for the check
Increase the ranks in the skill
DC: 5 + 1 per rank trying to obtain.
Mods:
Untrained: + 5 DC
Skills:
Physical: -5 DC
Military/ covert skills and basic: +5 DC
Intermediate: +5 DC
Advanced: +10 DC
I can see some feats for broad based mods +1, area specific +2 and skill specific +4 being made by me as well.
How to assign:
Players have an amount of attempts for free at each level, which are lost if unused before leveling.
(yes GM could allow a last burst of attempts before the level die is rolled)
High end creation:
A single roll can be used to set the upper limit available for each level, all attempts are successful, or individual checks for each check with a chance of failure can be done.
You can only attempt to add a new skill or rank (up to the skill maximum) if you have been successful with that skill. (GM call)
Gaining above the free attempts:
I also will be allowing more checks BUT they must go to a external palce like a gym or uni or such...
