Seraphine Vale
Human · Fighter 24
Class BAB advancement stops after character level 20. The epic attack bonus applies beyond 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 books through classes, feats, magic, equipment, companions, and final validation without losing the depth of 3.5.
Open the builderKey numbers show their work
Open the Rules Lens to inspect supported formulas and terms, prerequisites, available books, calculated consequences, and book mechanics that still need review.
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 book-aware rules archive
Search the current structured rules catalog and enable only the supported campaign book packs your table uses. Builder choices remain rules-validated and book-aware.
Search the archiveRules and lore, with receipts
Ask a character-aware 3.5 rules assistant for build guidance, mechanical explanations, item lore, or setting research. Answers include reviewed book, section, and page references; Vellum withholds an answer when those references cannot be verified.
Ask Vellum AIA book-grounded creative workshop
Generate names, backgrounds, mechanical progression plans, magic items, spells, and epic spells as saved artifacts. Deterministic checks identify what is verified and what still needs DM judgment; character changes always require an explicit preview.
