Wish+ is now the mightiest spell a mortal creature can cast. By simply speaking aloud, you can alter the very foundations of D&D according to your desires.

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

• You create one object of up to 50,000 gp in value that is a magic item. The object can be more than 300 feet in any dimension, appearing in an unoccupied space you can see on the ground.
• You allow twenty or more creatures that you can see to regain all hit points, and you end all effects on them described in the greater restoration spell.
• You grant ten or more creatures that you can see immunities to all damage types.
• You grant ten or more creatures you can see immunity to a single spell or other magical effect for 24 hours. For instance, you could make yourself and all your companions immune to a lich's life drain attack.

 
You might be able to achieve something beyond the scope of the above examples. State your wish to the GM as precisely as possible. The GM has great latitude in ruling what occurs in such an instance; the greater the wish, the greater the likelihood that something goes wrong. This spell might simply fail, the effect you desire might only be partly achieved, or you might suffer some unforeseen consequence as a result of how you worded the wish. 

Finally, there is a 0% chance that you can cast Wish+ ever again if you suffer this stress.
