How stat increases work:
Each career has its own advance scheme. This tells you which stats your character can increase. You can only increase these stats, and no others... you'll need a new career to increase different stats.
One stat increase is either +10 or +1 to a stat, depending if it's a percentage stat or not. So, for example, WS increases in +10 increments, while S increases in +1 increments. It cost 100 experience points per advance.
Advances are listed as +10, +20, +30 or +40 (or +1, +2, you get the idea). Each +10 is one advance. You cannot repeat these. So, the first time you increase WS, you can use a +10. To increase it further, you need an advance scheme that has at least a +20. So a + 20 is actually two advances of +10.
So you can never increase WS by more than +40 in total. You can't take a +10 more than once, even from another career.
Stat boosts from skills (such as +10 I from lightning reflexes) are not advances and don't count toward this limit. You can still buy a +10 I if you have lightning reflexes.
I wasn't sure if you could only upgrade each stat once or more than once
Only once until you get a better career.
