Antimagic Egg (Magic Egg)

This egg-shaped container of oil-darkened steel bears a single engraved rune. If the rune is touched and the command word spoken, the egg is activated. A “one-shot” magical device, it slowly melts away (causing no physical damage, even if held). All magical items within 30 foot must make a save (as their base material vs. magical fire at -5, plus item magical bonuses) or be drained. Each spell on a scroll as well as each dose of a potion must save separately.
Artifacts and helms “drained” by an antimagic egg are nullified and dead for 1d4+1 turns; chargeable items lose 1d12 charges and are dead for an 1d4+1 turns as well. Spellcasters within range who have memorized spells must save vs. spell or instantly forget one spell (selected at random). Natural, magical powers are unaffected, but cannot be used within the 30 foot range of the egg for 1d4+4 rounds after the egg is activated (the time the egg takes to entirely disappear).
The method of making such eggs is known to many priests and wizards, but those who know keep the secret. The Grafting is said to be a long and expensive process-thought by some to be the work of the arcane. Well-traveled sages, such as Otiluke of Oerth, know that the arcane try to purchase or destroy such devices whenever they can, and believe antimagic eggs to be weapons devised for use against the arcane. Otiluke believes the means of making such eggs to be among the earliest triumphs of human magic, or perhaps the work of renegade elves of long-time past. Elminster thinks them the work of illithids, perhaps working with humans or drow. To call these eggs “human invention” is pure hubris.
