Old World Rankings · Published 9 Sep 2026 · 2 min read

Build an Old World army list on OWR, on the web or in the app, with live validation.

Battle Builder is the army list builder built into OWR. On the web, go to oldworldrankings.com/builder or open it from your profile menu. In the app, tap Builder in the bottom tab bar. Sign in first: your lists sync between web, iPhone and Android.

Create a list

  1. In your library, choose Create List.
  2. Pick your faction, army type (Grand Army or an Army of Infamy) and points.
  3. Set Game format to the comp your event runs. The points presets change to match. See Army Comps and Game Formats.
  4. Leave Rules version on the current FAQ and Errata unless your event runs an older one.

Turn on Narrative mode if you want to build with list restrictions switched off.

Build and check the list

Use Add unit in a category, then choose options, weapons, mounts and magic items. Each category shows its cap and what you have spent.

The panel at the top lists Errors (the list is not legal) and Warnings (things still to do, such as taking a General). Tap one to jump to the unit that caused it. The list is legal when the panel is empty.

Tap any special rule, magic item or lore to read it in place. See Reading Rules and Stats by Phase.

Battle Builder is in beta and faction data is still being checked. Look over points and options before you submit a list to an event, and report anything wrong.

Your library

The library holds every list you have built, plus your upcoming events with their army list deadlines. Group lists into coloured folders and rate them to tell your club-night list from your GT list.
