Cap (General Help)

Skills and stats cannot be trained infinitely. Every skill and stat has a cap of 100 (note: "highlevels" [21+] can train stats (not skills!) above 100). At lower levels, skills are also not trainable past a certain point. This point being the "cap." The cap for both skills AND stats is the average stats required for your level (see 'help levels') plus fifteen (+15). So a thief of level 10 could only train his theft to 75, and can not train his intelligence above 75 either. Most likely the average first time player will never encounter this cap.

Note that skill-boosting items may improve your skill past the caps, however for consistency reasons trainers may refuse to train you in the skill more (even if its "base" level is below the cap) if you carry such an item.
