100 Wild Magic Surges

One hundred things that can go wrong (or right) when casting a spell!

    1. A caster teleports 25 ft. to the left of their location. A trail of fire appears from their starting position to their teleported position.
    2. The spell fails to take effect… until 1d4 rounds later.
    3. Something Fishy: the caster is left smelling of fish. The target of the spell also smells of fish. If the spell affects an area, the area smells of fish. If the spell produces a projectile the projectile becomes a fish(no change to damage type).
    4. All the players randomly change bodies for 1d4 rounds.
    5. It rains literal cats and dogs for one round, causing 1d4 bludgeon damage to any creature hit by a dog and 1d6 slashing damage to any creature hit by a cat.
    6. Feathers – The caster hair follicle’s sprout feathers of one type and in the next round, these fall off, or fly away and a round after, they sprout different feathers. This effect lasts a number of turns = d6+spell level . So the caster was casting Chain Lightning a 6th level spell. 6d6 turns.
    7. A genie offers the caster a Wish, but refuses to grant it and disappears.
    8. The caster can see one round into the future.
    9. Everyone in a 3d6 foot radius has to make a DC 15 Con save or falls asleep for 1d4 rounds.
    10. 2d8 gp fly out of the casters hands. 2d8 of them hit (if the second roll exceeds the first, they all hit), dealing 1d4-1 bludgeoning damage each.
    11. The caster and the target both get an intense sense of kinship and refuse to fight each other for 1d4 rounds.
    12. The caster loses containment of his or her magical power, which all goes pouring out to the nearest creature. The caster expends all his or her remaining spell slots and sorcery points, adding all the spell levels together (with each sorcery point counting as 1 level). The target takes 1d6 force damage for each spell level expended this way. If this damage kills the target, the leftover damage continues to the next closest creature, and so on until all damage has been applied.
    13. The spell builds up at the users magical implement, charging. The spell is not cast this turn, but next, dealing double damage to those hit.
    14. A force explodes out in a ring around the caster, knocking everybody back 5 feet (Fort save DC14, range 25ft)
    15. The caster begins to glow. (As Light spell, no save)
    16. The caster loses control of their bladder. Constitution save DC18 or they urinate on the spot.
    17. The user is driven mad by the spell, causing them to go into a barbarian rage for one minute.
    18. Your shadow detaches from you and becomes a shadow (the creature).
    19. You flash with golden light that seems to hang in the air around you. Everyone caught in this light (20 foot radius) receives double healing and cannot lie for the next 10 turns (one minute outside combat).
    20. The world seems to dim and plants seem to wilt around you. Everybody in a 20 foot radius takes double damage from necrotic damage and take one point of exhaustion on any critical failures for the next 10 turns (one minute outside combat).
    21. You feel very attractive… All unsecured objects and creatures in a 100 ft radius moves towards you by 5 feet.
    22. You feel like you really need to sneeze. Make a constitution saving throw with a DC of 10+your spell casting modifier. On a failure, you sneeze, and involuntarily cast prismatic spray (without consuming a spell slot) in the direction you are facing. On a successful save, you sneeze normally, without any ill effects.
    23. The world seems to slow to a crawl around you. You get to take 1 additional action.
    24. The smell of cinnamon fills the area in a 30-foot radius around the caster.
    25. A small songbird pops into existence in mid-flight 10 feet above the caster. Roll a d20. On a 1, the bird poops and it lands on the caster. On a 20, the bird poops and it lands on the target of the spell.
    26. The caster develops severe claustrophobia for 1d4 hours.
    27. A sinkhole, 20 feet deep and 10 feet in diameter, appears at a random location within 100 feet of the caster.

    36. The caster grows an extra finger on one of their hands. A remove curse spell or a successful DC20 medicine check can remove the finger.
    37. The spell is unexpectedly loud and everyone within 10 feet of you (including you) takes 1d6 thunder damage and the spell can be heard 600 feet away.
    38. The casters eyes catch on fire and their hands are covered in ice crystals. Any unarmed attack deals an additional 1d4 cold damage for 1d4 rounds.

    49. For the next 24 hours, the caster’s nose grows outwards by 1 inch every time they knowingly tell a lie. The nose returns to it’s previous size once the duration is up.
    50. For the next hour, the caster bursts into a fit of evil, maniacal laughter every time they open their mouth. Each time they do so, they must make a DC 13 Wisdom saving throw or be compelled to pull a minor prank of some kind. The nature of the prank is at the player’s discretion, so long as it is suitably mischevious and harmless.
    51. Every writing in a 10-foot radius of the caster immediately transforms into incredibly petty criticism of the caster. If the caster reads any of it, they must make a DC 10 Wisdom saving throw or believe whatever minor putdown the writing describes.

    62. The target for the spell becomes immobilized for 1 round, and until they succeed in a con save (DC 10).

    78. In the next 1d6 hours the caster grows 1d6 feet, but gains no mass, so a halfling would become an extremely tall thin creature. No negative effects purely cosmetic, can be reversed with remove curse.
    79. The casters eyes and veins glow in the dark for 1d6 days.

    93. Instead of the intended effect, 10d10 trees in the area grow mouths, and begin singing for 1d8 rounds. If the original spell was supposed to be a spell of healing, the song is a rousing chorus that washes away fatigue and ends any emotional (fear, charm, etc.) effect that is currently afflicting any that hear it. If the original spell was supposed to be an attack spell, the song is an irresistible tune that catches up all that hear it into singing it with the trees, and all the attitudes of the combatants is changed to neutral towards each other when the song ends. If the spell was supposed to be anything else, the song is a soothing song that makes the listeners sleepy, making it hard to take reactionary attacks until the song ends.
