11th Edition is here and so is GrimSlate's full support. Detachment Points, updated points for all factions, Leader/Support roles, and a one-click 10th Edition roster converter.

GrimSlate Now Supports Warhammer 40K 11th Edition

Warhammer 40,000 11th Edition launched on June 20, 2026 — and GrimSlate 4.0 brings full 11th Edition support to every part of the app. New army-building rules, updated points for all 34 factions, and a one-click converter for your existing rosters. Here's everything that's new.

Detachment Points: Build Armies the New Way

The biggest change in 11th Edition is how armies are built. Instead of picking exactly one detachment, you now spend a Detachment Points (DP) budget:

Battle Size

Points

DP Budget

Enhancements

Duplicate Limit

Incursion

1,000

2 DP

2 (4 Battleline)

Strike Force

2,000

3 DP

3 (6 Battleline)

Each detachment costs 1–3 DP. Take one army-wide 3 DP powerhouse, or combine two or three cheaper detachments — as long as no two share the same unique tag.

GrimSlate's builder handles all of it:

Add and remove detachments from the new multi-detachment configuration card, with a live DP counter

Unique-tag conflicts are detected automatically — incompatible combinations are flagged before you pick them

Every detachment for all 34 factions is in the app with its full rules, stratagems, and enhancements — including the brand-new 1 DP detachments introduced in the June Faction Packs

Enhancements from all your selected detachments appear together, with the new per-battle-size limits enforced

Leader and Support Characters

Characters now attach to units as either a Leader or a Support character, and a unit can have one of each. Assignments happen while you build your list — not at deployment.

In GrimSlate:

Attach options come straight from the official 11th Edition data, so you always see exactly which units a character can join

Support characters are clearly tagged, and the app warns you if one is left without a bodyguard unit (they can't operate independently)

Enhancements that grant new attachment options are supported too

Your tournament exports include every Leader and Support assignment

Updated Points for Every Faction

All unit costs, enhancement costs, and detachment DP values come from the new online Munitorum Field Manual, which Games Workshop now updates digitally. GrimSlate tracks it closely — when GW ships a balance update, we re-sync.

Convert Your 10th Edition Rosters

Your existing lists are completely safe. Rosters created before the update stay on 10th Edition rules and data — nothing changes unless you say so.

When you're ready, hit "Convert to 11th" on any 10th Edition roster:

1GrimSlate shows a full before/after points diff for every unit and enhancement

2Units retired from the new edition are flagged as Legends (they keep their points)

3Leader/Support roles are auto-assigned where possible

4You can keep a 10th Edition copy of the list with one checkbox

Also in This Update

New Core Rules reference — 2" engagement range, the new cover and Hidden rules, updated charges and reserves, one stratagem per unit per phase, and more

Datasheets show the official 11th Edition attachment lists and Support tags

Tournament exports (BCP, ITC, and print formats) include multi-detachment headers with DP costs

Public roster pages display all selected detachments with their rules and stratagems

What's Coming Next

A couple of things are still on the roadmap:

Battle Mode currently uses 10th Edition missions — the new Force Dispositions and terrain-objective missions are coming in a future update

Onslaught (3,000 points) DP budget is not yet confirmed by Games Workshop; we'll add it the moment it's official

Start Building
