Practice

Syntax: practice
Syntax: practice <skill|spell>

PRACTICE without an argument tells you your current ability level in all
the skills and spells available to you. You can check this anywhere.

PRACTICE with an argument practice that skill or spell. Your learning
percentage varies from 0% (unlearned) to a maximum between 80% and 100%,
depending on your class. You must be at a GUILDMASTER to practice.

The higher your intelligence, the more you will learn at each practice
session. The higher your wisdom, the more practice sessions you will
have each time you gain a level. Unused sessions are saved until you
do use them.
