Limited wish

The limited wish is a very potent but difficult spell. It will fulfill literally, but only partially or for a limited duration, the utterance of the spellcaster. Thus, the actuality of the past, present, or future might be altered in some limited manner. The use of a limited wish will not substantially change major realities, nor will it bring wealth or experience merely by asking.

The spell can, for example, restore some amound of the health or heal the wounds the wizard. It can reduce opponent hit probabilities or damage, increase duration of some magical effect, cause a creature to be favorably disposed to the spellcaster, mimic a spell of similar or lesser power, and so on. Greedy desires usually end in disaster for the wisher.

Note: This version of limited wish originally appeared in the 2nd Edition Player's Handbook for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
