D&D 5E Fumble charts for spellcasting?

[Matatabi]

I really like the fumble charts because in a layed back game it adds a bit of humor to the game (you attack with a horn and it gets stuck in the ground). But a few of the results wouldnt work with spellcasting (your weapon goes flying off 5 feet away from you).
Is there a fumble chart for spellcasting or if you happen to land on one that requires a weapon you just ignore it?

If it requires a weapon, substitute their spell component pouch or arcane/divine focus. If the spell they are casting doesn't require a material component, re-roll.

(What do you do if a monk fumbles on an unarmed attack?)

I actually normally play a monk. We just treat it like nothing happened if it rolls on something we cant do.

I love and recommend Nord Games' Critical Fail Deck for this. Each card has multiple entries, one of which is for spellcasting, and the entries are super colorful and creative.

Fair warning that, if you're lucky enough to have a group like mine, the effects can have some really gonzo consequences. The full account of what happened with our cleric and the zombie is, I'm afraid, not printable in this forum.

My 5E DM uses the Pathfinder critical and fumble decks and modifies the descriptions as needed!

I don't have fumble charts, but I did make school-based Wild Magic charts (my campaign has universal wild magic, with the magic more likely to go weird the higher level the magic). Sometimes it means the spell casts normally but with some additional effects (good or bad), and other times it converts into a different spell.

Some samples from Evocation:

21-22 You gain the ability to glow in the dark. The light is dim out to ten feet from you, and you become visible to other creatures as a point of light. You can choose whether to glow or not.
23-24 If the spell does damage, it only does half damage. You pulled the spell at the last minute.
25-26 The spell you just cast now deals acid damage instead of its normal type. If the type is already acid, it deals an additional 1d6 damage. If there is no damage, it does 1d6 damage to its target.
27-28 You cast Cone of Paste (5th level spell). All creatures in the target area have their movement slowed by 10 feet until they are outside the area of effect if they do not succeed on a Dexterity save.
29-30 Pick a theme song. Whenever you pass through a doorway it plays.

I would love Love LOVE to get a copy of these school-based magic fumble charts from you. If they're available for money somewhere, please let me know.

The actual purchase link for that Fumble deck doesn't seem to be working. It looks like something I would want to have though, and the Critical deck too.

Wait nevermind, it's working now

The Wild Magic chart might help inspire you.
- You turn blue (or some other garish un-natural color)
- A Modron (insert other Outsider here) appears for 1 minute and acts according to its nature.
- You cast a random Bard cantrip at the enemy instead of your desired spell
- Your tang is toungled and you cannot cast any Verbal-component spell until the end of your next turn.
- The God of Magic appears and scolds you personally for such miserably inept use of his Gift to the World
- The target turns into a potted plant. If anybody touches it, that person turns into a potted plant too. Each victim turns back to normal after 30 seconds.
- The target is able to cast your spell back at you on its turn, once only.
- Your spell component pouch disgorges a Lion (think Bullwinkle "watch me pull a rabbit out of my hat") which attacks the target, instead of the intended spell effect.
- As above except you get a Squirrel.

I made one when switching to 5e. It's mostly some stolen ideas from Paizo's critical fumble deck, and some made by myself. It's only for spells with attack rolls.
It could also apply when the opponent rolls a 20 on his saving throw. At least in cases where there's no partial successes.
