This spell fulfills any wish of the caster, but only for a limited time, and only partially. Thus, the past, present, or future might be altered, but only for the caster, and major realities, wealth, and experience cannot be created or modified. The spell could, for instance, restore some lost hit points to the caster (or all lost hit points, but only temporarily). It could modify die rolls, change the duration of a magical effect, cause a creature to be charmed, mimic a spell of 7th level or less, etc. Greedy or incautious desires often end badly for the caster.   The casting time is spent correcting the wording of the spell. Generally, the casting time is one round. Casting this spell ages the caster 1 year per 100 years of regular life span (so humans age 1 year, half-elves and halflings age 2, dwarves and gnomes age 4, and elves age 5).
