The only spell in the game that belongs to Sorcerers and nobody else, and it decided its whole personality would be a gambling problem.
Today we’re looking at a 1st level evocation spell called Chaos Bolt. Available to Sorcerers, and pretty much only Sorcerers, this is the one spell on the entire list that no other class gets to call its own. You hurl a wad of raw magic at somebody, roll to see what flavor of damage it deals, and if the dice feel like it, the bolt jumps to a new victim and does the whole thing over again. It is the closest the spellbook ever gets to pulling a slot machine lever and hoping.
Sitting at a range of 120 feet, a casting time of one action, and a duration of instantaneous, Chaos Bolt is a ranged spell attack that throws 2d8 plus 1d6 damage downrange. That is a big number for a first-level slot. The catch, and the reason this spell starts more comment fights than almost anything at its level, is that you do not pick the damage type. The dice do. And the part everyone has heard about, the wild magic sorcerer’s dream, is the leap: roll matching numbers and the bolt ricochets to another creature and keeps going.
The community angle here writes itself. Chaos Bolt lives in the long shadow of Chromatic Orb, it cannot be Twinned no matter how badly you want it to, and there is a famous math rabbit hole about stacking the odds of that leap until the bolt in theory never stops bouncing. We will get to all of it. Let’s start with the rules as written, and remember, you can always fight me in the comments if you read it different.
RAW
- Casting Time: 1 action
- Range: 120 feet
- Components: V, S
- Duration: Instantaneous
Here’s the text, straight from Xanathar’s Guide to Everything, page 151:
“You hurl an undulating, warbling mass of chaotic energy at one creature in range. Make a ranged spell attack against the target. On a hit, the target takes 2d8 + 1d6 damage. Choose one of the d8s. The number rolled on that die determines the attack’s damage type, as shown below.”
Then comes the table, and you want to know it cold, because it decides everything. A 1 is Acid, a 2 is Cold, a 3 is Fire, a 4 is Force, a 5 is Lightning, a 6 is Poison, a 7 is Psychic, and an 8 is Thunder.
“If you roll the same number on both d8s, the chaotic energy leaps from the target to a different creature of your choice within 30 feet of it. Make a new attack roll against the new target, and make a new damage roll, which could cause the chaotic energy to leap again.”
“A creature can be targeted only once by each casting of this spell.”
Let’s slow down, because almost every line here gets fumbled at somebody’s table.
“Make a ranged spell attack.” This is an attack roll, not a saving throw. You can whiff. You add your spellcasting modifier and proficiency, the target’s armor class decides whether it lands, and a natural 1 misses like any other attack. That already sets it apart from the save-based blasters at this level, where the enemy is the one sweating the dice.
“On a hit, the target takes 2d8 + 1d6 damage.” Two d8s and a d6, averaging 12.5 before anything else. For a first-level spell that is a genuinely fat hit. Hold onto those two d8s, though, because they are about to pull a second job.
“Choose one of the d8s. The number rolled on that die determines the attack’s damage type.” Here is the first thing people get backwards. You do not choose the damage type off a menu. You roll two d8s, each one is showing a face, and each face maps to a type on the table. You then pick which of your two dice to keep, and that die’s number is your flavor. Roll a 3 and a 6 and you may deal Fire or Poison, your call, but those are your only two options this cast. You wanted Force and rolled a 2 and a 5? Tough luck, it is Cold or Lightning today. The randomness is the entire spell, and whether that reads as a feature or a bug is the argument that follows this thing around forever.
“If you roll the same number on both d8s, the chaotic energy leaps.” This is the leap, and this is where people lose the plot. If your two d8s match, say two 4s, the bolt still hits the first target for full damage and then jumps to any creature you choose within 30 feet. You make a brand new attack roll and a brand new damage roll on the new target, and if those two d8s also match, it leaps again. There is no printed cap on how many times it can chain. On paper, one casting can clear a room. In practice the odds of any single roll matching are 8 in 64, which is one in eight, and the chance of stringing several matches in a row falls off a cliff fast. It is a lottery ticket stapled to a damage spell.
Two things people get wrong about the leap. First, the original target still takes its damage. The bolt does not abandon the first guy to chase the second, it hurts the first and then travels. Second, that leap needs a real creature within 30 feet to jump to, and it obeys the last line of the spell.
“A creature can be targeted only once by each casting of this spell.” This quiet little sentence is the anti-infinite-loop clause, and it is doing heavy lifting. Without it, two enemies standing next to each other could ping-pong a matched bolt back and forth until one of them died. With it, every leap has to find a fresh body. Run out of new creatures within 30 feet and the chain stops no matter how hot your dice are. So the dream of a bolt that bounces forever between two goblins is dead on arrival, by design.
At Higher Levels.
“When you cast this spell using a spell slot of 2nd level or higher, each target takes 1d6 extra damage of the type rolled for each slot level above 1st.” Notice what scales and what stubbornly does not. You add a d6 per level rather than a d8, and that gap is a deliberate leash, because the two d8s are the dice that trigger the leap, and letting you pile on more of them would send the bounce odds through the roof. So Chaos Bolt out of a 3rd-level slot is 2d8 plus 3d6. More damage, exact same two-d8 engine driving the chaos.
Limits and Cheeses
Quick version here, the deep dive is the companion post.
The big one, the question every sorcerer eventually asks: you cannot Twinned Spell this. Twinned Spell only works on a spell that is incapable of targeting more than one creature at its current level, and because Chaos Bolt can leap to a second creature all by itself, it is disqualified before you even start. Jeremy Crawford confirmed this years ago and it has been the rule since. Chromatic Orb can be Twinned. Chaos Bolt cannot. That one line is most of the reason these two spells feel so different in play.
The other headline is that Chromatic Orb comparison, because Chromatic Orb does 3d8, lets you pick your damage type freely, upcasts with a d8 instead of a d6, and can be Twinned. On paper it wins the majority of the time. Chaos Bolt’s answer is that it needs no 50 gold diamond, it can roll up Force or Psychic damage that Chromatic Orb flat cannot produce, and it has that leap. Which one is better is a fight I am not going to fully settle here, because the uses post is where I lay out every trick for juicing the bounce and every spot where the chaos actually earns its keep. All the odds-stacking builds, the Elemental Adept feat, the Empowered Spell metamagic, and the backgrounds that smuggle this spell onto classes it was never meant for, they all live over there.
2014 versus 2024, or, is there even a 2024 version?
Short answer, no, and it is the same story as a few other Xanathar’s spells. Chaos Bolt did not get reprinted in the 2024 Player’s Handbook. There is no updated version to hold it up against. You are casting the Xanathar’s text, word for word, and it runs fine under the 2024 rules.
But here is the part I find fun, because the 2024 team clearly did not forget this spell existed. The new Sorcerer got a fresh cantrip called Sorcerous Burst, over on page 318, and it borrowed Chaos Bolt’s whole soul. You deal 1d8 of a type you choose, and if you roll an 8 on that d8, you get to roll another d8 and add it, and you can keep chaining those extra dice up to your spellcasting modifier. Same idea, a spell that snowballs out of control when the dice run hot, except now it is a cantrip and the trigger is cleaner. So while Chaos Bolt itself stayed behind in 2017, its escalating-chaos DNA very much walked into the new edition wearing a different hat.
If somebody at your table swears Chaos Bolt got changed in 2024, it didn’t, because it wasn’t in the book to change. Sorcerous Burst is the spiritual sequel, not a fresh coat of paint on this one.
History
Now the history, and it is a short chapter, because Chaos Bolt is a true 5e original. There is no 1st edition Chaos Bolt, no 3.5 Chaos Bolt, no 4e Chaos Bolt. The name and the mechanic were both born in fifth edition, so there is no cross-edition arc to trace here, and anyone who claims they slung this back in AD&D is having you on.
What it does have is a tidy fifth-edition paper trail. The spell first surfaced in the April 2017 Unearthed Arcana packet called Starter Spells, which was a batch of new low-level playtest options. It tested well enough that later that same year it got made official in Xanathar’s Guide to Everything, in November 2017, on page 151, as a Sorcerer-exclusive. A year after that it earned a second printing in Guildmasters’ Guide to Ravnica, page 67, where the book handed it to the Izzet League, Ravnica’s guild of mad-scientist mages who fuse fire and lightning for the fun of it. If you have ever wanted a spell for a chaos-loving lab-coat wizard type running experiments that occasionally explode, that Ravnica flavor fits like a glove.
So the entire life story of Chaos Bolt is really just its 5e résumé: a playtest, a hardcover debut, a guest slot in a Magic: The Gathering crossover book, and then a polite absence from the 2024 update while its cantrip cousin picked up the torch. Short career, very loud personality.
Opinion
Chaos Bolt is the spell I want to love more than I actually do. The fantasy is perfect. You are a sorcerer, the magic leaks out of you a little wrong, and every so often it goes feral and chains through a whole pack of enemies while the table gasps. On a good night that is the coolest thing that happens all session. On a bad night you roll a 2 and a 5 into the one enemy resistant to cold and lightning, deal a limp middling hit, and quietly wish you had learned Chromatic Orb like a responsible adult.
Here is my honest read. As a plain first-level blast, 2d8 plus 1d6 sits above the curve, so this is never a trap in the raw-numbers sense. What holds it back is that its coolest feature, the leap, is a coin flip you lose seven times out of eight, and its next-best feature, choosing the damage type, is capped at whatever two faces the dice happen to show you. It is a very fun spell and a slightly maddening one, and both of those are true at the same time. If you like rolling dice and letting the whole table lean in, play it and never apologize. If you want a blaster you can set your watch to, you already know what the diamond costs.
I want to hear where you land, though. Is Chaos Bolt the pride of your sorcerer, or the spell you keep meaning to swap out and never do? And have you ever had the bolt chain three, four, five times and erase an entire encounter in one cast? Tell me in the comments below, go read the companion post for every way people have tried to weaponize that leap, and until next time, roll high and stay ridiculous.
