Changes

The use option on the sculpting wand changes the power of the wand:

Uses 1QL each sculpt: "You rub the wand and it makes a barely audible humming sound."

Uses 3QL each sculpt: "You rub the wand and it makes a humming sound."

Uses 5QL each sculpt: "You rub the wand and it makes a loud humming sound."

Each "sculpt" digs the amount of dirt that it uses QL, therefore from the default 60QL you can dig 60 dirt.
