GrimSlate Now Supports Warhammer 40K 11th Edition — Detachment Points, New Points & Roster Converter

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:

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:

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:

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:

Battle Mode Is Now 11th Edition

Battle Mode now includes the complete Chapter Approved 2026-27 mission system: Force

Dispositions, all 25 directed primary missions, fixed and tactical secondaries, and all 45

terrain-layout combinations. Tactical cards remain in hand until scored or discarded, and scoring

is capped automatically by round and category.

Onslaught (3,000 points) remains available for casual games while its Detachment Point budget is

confirmed.
