A really limited wish lets you create nearly any type of really limited effect. For example, a really limited wish can do any of the following things.

Duplicate any sorcerer/wizard spell of 4th level or lower, provided the spell does not belong to one of your opposition schools.
Duplicate any non-sorcerer/wizard spell of 3rd level or lower, provided the spell does not belong to one of your opposition schools.
Duplicate any sorcerer/wizard spell of 3rd level or lower, even if it belongs to one of your opposition schools.
Duplicate any non-sorcerer/wizard spell of 2nd level or lower, even if it belongs to one of your opposition schools.
Undo the harmful effects of many spells, such as bestow curse.
Produce any other effect whose power level is in line with the above effects, such as a single creature gaining a +10 on its next attack roll or taking a -5 penalty on its next saving throw.
A duplicated spell allows saving throws and spell resistance as normal, but the save DC is for a 5th-level spell. When a really limited wish spell duplicates a spell with a material component that costs more than 50 gp, you must provide that component (in addition to the 100 gp diamond component for this spell).

And while we’re at it, might as well finish the regression

A pseudo-wish lets you create nearly any type of really limited effect. For example, a pseudo-wish can do any of the following things.

Duplicate any sorcerer/wizard spell of 2nd level or lower, provided the spell does not belong to one of your opposition schools.
Duplicate any non-sorcerer/wizard spell of 1st level or lower, provided the spell does not belong to one of your opposition schools.
Duplicate any sorcerer/wizard spell of 1st level or lower, even if it belongs to one of your opposition schools.
Duplicate any 0-level non-sorcerer/wizard, even if it belongs to one of your opposition schools.
Produce any other effect whose power level is in line with the above effects, such as a single creature gaining a +5 on its next attack roll or taking a -3 penalty on its next saving throw.
A duplicated spell allows saving throws and spell resistance as normal, but the save DC is for a 3rd-level spell. When a pseudo-wish spell duplicates a spell with a material component that costs more than 5 gp, you must provide that component (in addition to the 10 gp diamond component for this spell).
