Seraphine Vale
Human · Fighter 20 / Legendary Dreadnought 4
Normal class progression ends at character level 20. Epic progression is applied after the gate.
Epic level is a first-class system
Cross level 20 deliberately—not accidentally.
Epic play changes the mathematics of a character. Vellum keeps it behind explicit campaign gates, then applies the correct post-20 advancement model without disturbing ordinary characters.
Depth without the spreadsheet
A builder before the session. A command center during it.
Vellum turns the enormous surface area of 3.5 into a coherent workflow, while keeping the machinery visible whenever you want to inspect it.
A guided 13-stage builder
Move from identity and campaign sources through classes, feats, magic, equipment, companions, and final validation without losing the depth of 3.5.
Open the builderEvery number shows its work
Open the Rules Lens to inspect formulas, terms, prerequisites, source provenance, unresolved imports, and the exact consequences of every choice.
Inspect calculationsA sheet built to be played
Track hit points, conditions, rounds, resources, attacks, spell preparation, dice, rests, inventory charges, notes, and companions at the table.
Open the play sheetA source-aware rules archive
Search the compiled PCGen library, enable only the books your campaign uses, and retain provenance instead of flattening thousands of options into a mystery list.
Search the archiveRules and lore, with receipts
Ask a character-aware D&D specialist for build guidance, mechanical explanations, item lore, or setting research. Grounded answers cite the exact book and page and label uncertainty instead of inventing canon.
Ask Vellum AIA complete creative workshop
Generate names, backgrounds, level-by-level builds, magic items, spells, and epic spells as saved artifacts. Deterministic checks and an explicit preview keep every character change under your control.
