Change the rate at which skills are learned
 

Is there a DB setting that can be changed to alter the normal rate at which skills get learned? Skills like Fletching, Offense, Defense and the combat skills (1HS or kick) out in the game environment (not from Guild Masters).

From just browsing common/ruletypes.h it looks like the rule Character:SkillUpModifier may do what you want.

The default is 100 (it is a percentage, so 100% = 'normal rate'). Changing it to 200 should make skills go up twice as fast (technically it would double your chance of getting a skillup each time you use the skill). You would update this in your rule_values table.
