Apprentice's Egg (Magic Egg)

When a wizard of Krynn declares an alignment and passes the Test of High Sorcery, he or she is apprenticed to a greater wizard to learn the secrets of the craft. One such secret is the manufacture of magical items, and the apprentice's egg is a minor part of this training, usually forgotten by more accomplished wizards.
The apprentice's egg is an inch-long magical construct used to hold the energies of a single cantrip spell in place, to be released when the egg is destroyed. The exact effect of each cantrip depends on the creator's wishes (subject to the DM's approval). Apprentice's eggs each cost 10 stl and take one day to produce. The egg can be thrown up to 30', and the spell it contains will be released at the point of impact, if the egg fails an item saving throw as glass (see “Grenade-Like Missiles” in the DMG for targeting information). As apprentice's eggs are made without use of enchant an item or permanency spells, they are somewhat unreliable, having a percentage chance of failing to work (rolled when the egg impacts) equal to the maker's intelligence subtracted from 25. A wizard with a 9 Intelligence could make eggs with a 16% failure rate, and one with an 18 Intelligence could make eggs with a 7% failure rate.
Some dragons are said to have learned the methods for creating these items, using them for their own amusement, though they would never admit it to any but their own kind.
