Ivory Plume of Maat (Magic Brooch)

This small, exquisitely crafted brooch, shaped like a feather, was created by a great paladin, the beautiful fighter Maat. She was a many-talented mortal, and strove always to promote good over evil. Her device is said to enable the user to follow in her noble footsteps, doing good deeds and furthering the cause of law and justice.
The plume is 3 inches long, made of very fine ivory. The plume is active when acquired. Knowledge of the powers is granted immediately, telepathically, to any user who is a paladin or good knight. Any other would-be user must gain the knowledge through a contact other plane or commune spell, by asking Maat directly. Each of the following powers is activated by mental command alone:
Suggested Powers: (All abilities are at 20th level.) Dispel evil, geas, continual light, turn (as 20th-level priest), lie detection, know alignment, choose best option (duration one turn; affects one choice), purify food and water, repair normal objects (affects up to 100 pounds of nonmagical material), remove fear, saving throw bonus (+4 bonus), immune to disease (range touch; affects all nonmagical diseases; duration 18 turns), immune to energy drain (range touch; duration six turns).
Suggested Handicaps: When first used, a wall of stone forms as a closed cylinder around the user. However, if the user closes his or her eyes, thinks of justice (or Maat), and steps forward, the wall vanishes when touched. The wall is completely invulnerable to outside attacks, including a wish. If the wall is destroyed or damaged by the user, he or she takes double damage from all physical attacks (no saving throw, and unremovable, as a handicap). Secondly, alignment changes to a lawful bent; if already lawful, the character becomes more rigidly so, and works more actively to defeat chaos.
Magic error: An 80% chance of error applies whenever the user casts a spell (or uses a magical device requiring a command word) to harm any lawful or neutral creature that has no evil intention.
Suggested Penalties: Whenever the item is touched, and if the creature touching the plume is chaotically-aligned or has evil intentions, disintegrate is cast with no saving throw. If the user slays a lawful creature, he or she is immediately reduced to -10 hp, and dies (no saving throw). The following have standard chances of either occurrence:
* Harden: A volume of up to 30,000 cubic feet of mud, mire, swamp, or other muck suddenly dries completely, if within 120 feet of the user.
* Opponents: Id4 chaotically-aligned enemies magically materialize out of the air, within 30 feet of the user. All the creatures are of one type; the type has a number of Hit Dice equal to 31-50% (ld20+10) of the user's levels. The creatures are native to the user's plane of existence (consider undead as native to any plane). Each opponent has maximum possible hit points. Neither side has surprise.
