Entropy and Chaos Magic
Wild Magic trope) or, more fancifully, "entropic magic" or variants on that name. Sometimes appears in settings with an Order Versus Chaos cosmology, but can pop up anywhere. It can function in many different ways, but frequent traits include: high randomness and uncontrollability, probability manipulation, and inducing accelerated decay and destruction, depending on how the writers understand the concept of chaos and entropy. "Entropy" in particular is one of these scientific concepts which appeals to writers due to its cool, sinister-sounding name and its association with decay. In real life, "entropy" is a physical concept, roughly defined as a measure of disorder and chaos of a given system. Per the second law of thermodynamics, the entropy of an isolated system can only grow, never decrease; the only way to decrease the entropy is for some external force to do work on itnote . Since the universe itself (as far as we know) is an isolated system with no external forces that can affect it, this suggests that eventually it will succumb to "heat death of the universe": eventually all organized systems will break apart into a chaotic, uniform soup. Hence why chaos-based entities tend to have an Omnicidal Maniac vibe to them. Might be related to Antimatter, Power of the Void, and Casting a Shadow.

- In The Last Draconequus, the protagonist is Discord, a god of Chaos.
- In the Chalion series, the demons bound by sorcerers are innate creatures of chaos. One way to keep a demon tame and easier to control is to 'shed' entropy, by causing little forms of decay, rust, or rot. (In one case, a sorceress caused milk to sour and wine or beer to go bad, at this one particular inn, in order to keep her demon occupied. Another powerful but poorly-trained sorceress used the entropic powers to aid in laying siege to a fortress, destroying stored food, potable water, and many of the weapons.) Inversely, using sorcerous magic to undo some form of destruction is 'extremely difficult, but possible. (A sorcerer mentioned having reconstructed a burnt letter, at great cost.)
- The initial impetus for the main plot of the sixth The Dresden Files book is when Harry is hired to deal with an entropy curse that kills its targets in strange and unusual ways. A previous victim is killed after being hit by a car... while water-skiing. Harry manages to intercept and redirect another use of it that causes a frozen turkey to fall out of a passing aircraft and pulverise an attacking Black Court vampire and just for extra value, cause the cooking timer to pop out and ding.
"For my next trick, Anvils!"
- Isyllt, the heroine of Amanda Downum's The Necromancer Chronicles series, is a necromancer and an entropomancer, the latter being a somewhat related but much rarer ability. She can accelerate, focus and control decay; for example, she causes a steel lock to rust away to dust in less than a minute.
- In The Saga Of Recluce pure Chaos is basically pure energy, but it has entropic side effects. Chaos mages age faster than normal humans, the wine they drink turns to vinegar before they're finished with it (or even after a minute or two for very powerful mages), books they read fall apart after a few years, and the city where the chaos mage guild is located is covered in a thin layer of fine white dust formed from Chaos energy slowly destroying the stones of the city.
- In a variation, Aornis Hades in the Thursday Next series manipulates entropy to affect chance. Specifically, by lowering entropy in order to cause improbable and fatal accidents. This has the side-effect of causing numerous, unrelated coincidences to pile up just prior to the accident—long enough for Thursday to realize the attack is coming.
- The Lone Power in the Young Wizards series has the main goal of bringing death to the multiverse by spreading entropy everywhere (he's also responsible for the creation of entropy, by the way), and his powers are wizardly in nature. Conversely, the proper application of wizardry can slow entropic decay.
- In Mistborn, this is Ruin's whole schtick, He is a living force of intelligent decay and entropy, seeking only to unmake the world. Appropriately enough, the magic system he empowers - hemalurgy - requires blood sacrifice to work, making it a power that can only be accessed through destruction.
- In Shadow Ops, entropy is the domain of Negramancy. Anyone with this power is a One-Man Army; the only known person with this power is able to destroy most of a fully-staffed military base of soldiers specially trained to fight magic-users in moments by simply making their equipment and bodies decay in seconds.
- The "wild magic" which is the Applied Phlebotinum of The Chronicles of Thomas Covenant books.
- Demons of the first choir in Pact are described as "entropy distilled" and "the antithesis to creation," and specialize in removing things from creation and leaving nothing in their place. There's no way to restore what was lost, and in many cases no way of knowing what was lost at all. It's speculated that the entire universe is itself composed of fragments of things they've devoured.
- Free Magic from The Old Kingdom, which is made up of all the powers left over from when the Charter was made, most of which are inimical to ordinary life. Notably, unlike the heavily rule-bound Charter magic, Free Magic has almost no rules at all - so long as you have sufficient strength of will and a strong enough source of it, you can do just about anything (though it's best at tearing things down). Of course, there are side effects...
Live Action TV
- Buffy the Vampire Slayer had Ethan Rayne, who worshiped chaos and often used chaos magic.
- Dungeons & Dragons
- Cleric spells from the "Chaos" domain. Most are generic Status Buffs which just happen to function against law-aligned creatures, but they also include Shatter (damages crystalline objects), Chaos Hammer (an offensive spell which takes the form of "a multicolored explosion of leaping, ricocheting energy") and Animate Objects.
- There was at least one prestige class in 3.5 DnD called the "entropmancer" who used a "shard of entropy" as its main weapon. They kinda screwed up the whole physics thing there (a "shard of entropy" makes about as much sense as "a piece of temperature"), but the thematic link is obvious.
- The 2nd Edition supplement Tome of Magic had Wild mages and the Chaos sphere for priests. Both emphasized chaotic spells with random results.
- After the Time of Troubles the Forgotten Realms developed Wild Magic Zones, where any magic use could cause a random Wild Magic Surge which was often quite dangerous.
- The Wand of Wonder (several varieties), which had a different effect each time it was used.
- In 4th Edition, Sorcerers can choose Wild Magic as a spell source, which is described as channeling power from the Elemental Chaos. To go along with the theme, many Wild Magic powers daze or stun enemies or have an effect determined randomly via die roll. Even boons from various Wild Magic features are determined randomly.
- The Euthanatos in Mage: The Ascension are masters of the Sphere of Entropy. In broad strokes this means they can tell when things are going to break down and they can make things break down.
- In Mage: The Awakening entropy gets divided into two Arcana. Fate allows manipulation of probability while Death includes decay (starting with objects at the basic level, living and undead beings at a moderate level of skill, and destroying spells and stored Mana at master level).
- Red magic in Magic: The Gathering is the most geared toward "chaos," with more cards with random or semi-random effects (mostly governed by coin flips) than any other color. Black has the most cards with "entropy" themes, although Green also gets into the mix with cards themed around natural decay.
- Entropomancers in Unknown Armies have power over luck and accidents, and gain power by deliberarely putting themselves in risky situations. They're earned their nickname of "Bodybags" honestly.
- Anarchy Mages in Ponies and Parasprites. These characters have sought out and learned from Discord himself. They use a Pandemonium Spark to channel the powers of the God of Chaos in much the same way a Cleric from Dungeonsand Dragons would. These mages have a tenuous grasp of their powers, meaning that their channels can and will go wildly out of control. note
- Warcraft: Several names of demons are based on the word Entropy. Demons in Warcraft III use chaos magic, and also have a number of "chaos" spells.
- Chaos Knight from DotA uses this.
- Fall from Heaven
- The entropy magic sphere is associated with the most the main evil god, and its spells relate to decay and corrosion. Entropy magic nodes act as a source of Hell Terrain, and any mage who uses the magic will come back to life as a slave of the Legions of Hell upon death.
- The chaos magic sphere is a flavor 1 chaos type, and is associated with the god of war (in a Anarchistic, everyone fights everyone, sense.), who is a fallen, evil god as well.
- Lords Of Magic's chaos faith uses flavor 1 spells.
- Heroes of Might and Magic IV has a spell school literally called Chaos Magic, and consists mostly of direct damage spells. Heroes of Might and Magic V has an entire school devoted to destructive spells, as well.
- Dungeon Crawl has Annihilations. Exactly What It Says on the Tin.
- ADOM features a variety of magicians devoted to Chaos, including the Chaos Archmage, guardian of the elemental Mana Temple. His powers are no more random than those of any spellcasting enemy, but he's much meaner than most of them. Like most of the other Chaos-themed creatures in the game, he can also corrupt your character with a melee touch attack, which produces a series of randomized warping effects.
- Entropy magic in the Dragon Age series consists mostly of curses and other sinister powers, and closely connected to The Fade.
- The Bonus Boss and True Final Boss of The Reconstruction have "Chaos" as their element, as opposed to a certain optional character with "Order" as his element. Both end up effectively Non-Elemental.
- Entropy is an element in, well, Elements.
- In Dungeon Siege III, this is used by Reinhart though the spells are more like Formulaic Magic that focus on DPS.
- The Secret World has Chaos Magic, which incorporates both increases in entropy and manipulation of probability. Oddly enough, it's mainly used by the Dragon, who oppose any form of stagnation - as in, exactly what entropy causes. note
