Set your options and generate spell ideas
In Dungeons & Dragons, spells define how magic works at your table — damage, control, healing, divination, and everything between. A DnD spell generator speeds up homebrew design when you need fresh ideas instead of reskinning the same official list.
This tool is built for dungeon masters and players who want structured spell concepts fast. Each roll gives you a naming hook, mechanical profile, and effect summary you can turn into balanced homebrew, NPC abilities, scrolls, or faction signature magic.
Muxgen's DnD spell generator runs in your browser with 1,881,600,000+ unique combinations and optional batch export. It is a fan-made planning aid — not affiliated with Wizards of the Coast — and works best when you still balance damage dice, saves, and wording against published spells of the same level.

Where this spell generator fits beside rulebooks, name tools, and open-ended AI chat.
Official spells are balanced and legal. This tool invents new concepts so your world is not stuck recycling Fireball forever.
Empty templates stall. Structured name, profile, and effect fields give you a draft to edit instead of a blank page.
Name tools invent titles. This page also rolls school, casting profile, and tactical effect in one click.
Chat can invent freely but drifts. Fixed fields and level filters give repeatable, copyable prep output.
Keep random magic fun — and fair — when it hits the table.
Compare damage, control, and duration to official spells of the same level before players get the draft.
A strong effect that also requires concentration may be fine — or overtuned if it stacks with existing concentration staples.
Expand the effect summary into save type, targets, and what happens on success/failure before session night.
Bonus-action casting plus strong main actions can break action economy. Cap or condition those designs carefully.
When building a cantrip list or 9th-level villain kit, set the level filter so the batch matches your intent.
Keep or rewrite M components so rituals and loot feel tactile — then decide if the component is consumed.
Practical guidelines for smoother, fairer custom magic at your table.
Power scales heavily with casting time and concentration requirements.
Give spells obvious save types, ranges, or positional weaknesses.
