Test your build before you commit.
Ever fall in love with a character concept — then get to the table and find it just doesn't perform? The Proving Grounds shows you realistic expected damage under real play conditions: a full adventuring day, real AC, and choices that account for staying alive — not theoretical maximums you'll never reproduce.
Live now: all 12 PHB classes and all 48 core subclasses, plus the popular multiclass builds — Sorcadin, Sorlock, Padlock, gishes and more. Real spell and feature picks, not flat averages. Artificer and expansion-book content aren't in yet.
A damage-per-round calculator. Pick a class, subclass, weapon, and feats — watch your damage update live across the levels that matter (7, 11, 15, 20). See where every point of damage comes from and what each option is worth. No setup, no account.
Open the calculator CatalogBrowse builds that are known to work — not just on paper, but at an actual table, accounting for survivability and real play. See exactly what each one is expected to do at every tier.
Browse the buildsWhen a YouTuber says a build does X damage, they usually mean under ideal, cherry-picked conditions. Optimizer spreadsheets are accurate but assume you already know how to drive them. The Proving Grounds sits in the gap: accessible enough for anyone, honest about what you'll actually get. Every number is checked against an authoritative math model before it ships.
The calculator and Build Finder are free, always. Patrons get level-by-level build breakdowns — the reasoning behind every choice — plus early access to new subclasses and personal build requests.
