If you are carrying it for its magic resistance, it is recommended to find a source of worn magic resistance before challenging the Wizard of Yendor, since he can steal it.

The intelligence check when applying a crystal ball now uses a d8 instead of d20 if it is your own quest artifact, or d16 for other blessed crystal balls.
Crystal balls are now generated with 3-7 charges. Uncursed charging adds 1-2 charges up to the maximum of 7. Blessed charging increases the number of charges to 7 and also blesses the ball. Cursed charging removes all charges and curses the ball.Applying a cancelled crystal ball now destroys it, regardless of whether or not it is an artifact.
Many variants implement L's Itlachiayaque Patch, which has the Orb of Detection replaced by Itlachiayaque, a lawful-aligned shield of reflection with some similar properties. xNetHack implements this patch, but additionally allows Itlachiayaque to be invoked and used like a crystal ball; EvilHack instead replaces the Orb with Xiuhcoatl, a lawful atlatl.
This Orb is a crystal ball of exceptional powers. When carried, it grants ESP, limits damage done by spells, and protects the carrier from magic missiles. When invoked it allows the carrier to become invisible.
