Sources & Attribution
Every piece of rules content in Data Dungeon is served via Open5e and comes from one of the open-licensed source documents listed below.
- Advanced 5th Edition (A5E): uses 10-level exhaustion, Fortitude/Reflex/Will saves, and superiority-die maneuvers. Our engine uses 5e exhaustion and ability saves — A5E content plays mechanically as 5e.
- Class-feature depth: SRD-12 classes get hand-authored Combat-tab modules (Rage, Action Surge, Hunter's Mark, etc.). Tome of Heroes classes appear as classes and track HP / saves / spell slots, but their features render as prose on the Features tab — no bespoke counters.
- Duplicate spells / items across sources: Fireball is in SRD 2014, SRD 2024, and at least one third-party source. Pickers dedupe by name and pick the version that matches your character's ruleset; other versions surface as "also in" badges on the same card.
- Species mechanics aren't enforced. A 2014 Elf's +2 DEX vs. a 2024 Elf's background ASI is yours to apply on the ability-score step. The app stores species as a name, not as a bundle of bonuses.
- Community-contributed sources ("Spells That Don't Suck", "Elderberry Inn Icons") are less rigorously edited than SRD / Kobold Press / EN Publishing content. Review before adopting at a serious table.
SRD 2014 + SRD 2024 are the baseline for every character — you can't turn those off (they're what WotC opened under the licenses). Other sources are opt-in per character so strict tables stay strict and extended-content tables get the full catalogue. DMs can further restrict allowed sources at the campaign level.
