Wish is the mightiest spell a mortal creature can cast. By simply speaking aloud, you can alter the very foundations of reality in accord with your desires.

The basic use of this spell is to duplicate any other spell of 8th level or lower. 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:

Object Creation. You create one object of up to 25,000 gp in value that isn't a magick item. The object can be no more than 100m in any dimension, and it appears in an unoccupied space you can see on the ground.

Instant Health. You allow up to twenty creatures that you can see to regain all hit points, and you end all effects on them described in the Esuna spell.

Resistance. You grant up to ten creatures that you can see Resistance to a damage type you choose. This Resistance is permanent.

Spell Immunity. You grant up to ten creatures you can see immunity to a single spell or other magickal effect for 8 hours. For instance, you could make yourself and all your companions immune to a lich's life drain attack.

Sudden Learning. You replace one of your feats with another feat for which you are eligible. You lose all the benefits of the old feat and gain the benefits of the new one. You can't replace a feat that is a prerequisite for any of your other feats or features.

Roll Redo. You undo a single recent event by forcing a reroll of any roll made within the last round (including your last turn). Reality reshapes itself to accommodate the new result. For example, a wish spell could undo an opponent's successful save, a foe's critical hit, or a friend's failed save. You can force the reroll to be made with advantage or disadvantage, and you can choose whether to use the reroll or the original roll.

Reshape Reality. You might be able to achieve something beyond the scope of the above examples. State your wish to the DM as precisely as possible. The DM 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. For example, wishing that a villain were dead might propel you forward in time to a period when that villain is no longer alive, effectively removing you from the game. Similarly, wishing for a legendary magick item or artifact might instantly transport you to the presence of the item's current owner. If your wish is granted and its effects have consequences for a whole community, region, or world, you are likely to attract powerful foes. If your wish would affect a god, the god's divine servants might instantly intervene to prevent it or to encourage you to craft the wish in a particular way. If your wish would undo the multiverse itself, threaten the City of Sigil, or affect the Lady of Pain in any way, you see an image of her in your mind for a moment; she shakes her head, and your wish fails.

The stress of casting this spell to produce any effect other than duplicating another spell weakens you. After enduring that stress, each time you cast a spell until you finish a long rest, you take 1d10 DARK damage per level of that spell. This damage can't be reduced or prevented in any way. In addition, your STR drops to 3, if it isn't 3 or lower already, for 2d4 days. For each of those days that you spend resting and doing nothing more than light activity, your remaining recovery time decreases by 2 days. Finally, there is a 33% chance that you are unable to cast Wish ever again if you suffer this stress.
