True Wish

True Wish is the power held only by those made gods.

The basic use of this spell is to duplicate any other spell. You don't need to meet any requirements in that spell, including costly components. The spell simply takes effect.

Alternatively, you can create one of the following effects of your choice:

• You create one creature or object.
• You allow creatures that you choose to regain all hit points, and you end all effects on them.
• You grant creatures that you choose resistance or immunity to a damage type you choose.
• You grant creatures that you choose resistance or immunity to a single spell or other magical effect.
• You undo a single recent event by deciding the result of any roll made within the last round (including your last turn). Reality reshapes itself to accommodate the new result.

 
You may achieve something beyond the scope of the above examples. State your wish to the DM.
