Granted. You can speak every language in the world because the nazis won world war II, and now the only remaining language in the world is German. On the other hand, the cake is nice.
I wish I had any one of the following:
Duplicate any wizard or sorcerer spell of 8th level or lower, provided the spell is not of a school prohibited to you.
Duplicate any other spell of 6th level or lower, provided the spell is not of a school prohibited to you.
Duplicate any wizard or sorcerer spell of 7th level or lower even if it’s of a prohibited school.
Duplicate any other spell of 5th level or lower even if it’s of a prohibited school.
Undo the harmful effects of many other spells, such as geas/quest or insanity.
Create a nonmagical item of up to 25,000 gp in value.
Create a magic item, or add to the powers of an existing magic item.
Grant a creature a +1 inherent bonus to an ability score.
Remove injuries and afflictions. A single wish can aid one creature per caster level, and all subjects are cured of the same kind of affliction. For example, you could heal all the damage you and your companions have taken, or remove all poison effects from everyone in the party
Transport travelers. A wish can lift one creature per caster level from anywhere on any plane and place those creatures anywhere else on any plane regardless of local conditions.
Undo misfortune. A wish can undo a single recent event.
