The Warhammer 40K 11th Edition Army Builder
GrimSlate is fully migrated to 11th Edition: Detachment Points, every current detachment with full rules, updated points for all factions, and automatic updates for existing rosters.
Everything We Updated for 11th Edition
The whole app has been migrated — data, rules, validation, exports, and guides. Here's what that means for your army building.
Detachment Points, Explained
11th Edition's biggest army-building change: instead of picking exactly one detachment, you spend a DP budget. Take one big 3 DP detachment, or combine two or three cheaper ones — GrimSlate tracks the budget and blocks illegal combos (two detachments can't share the same Unique Tag).
| Battle Size | Points | DP Budget | Enhancements | Unit Copies |
|---|---|---|---|---|
| Incursion | 1,000 pts | 2 DP | 2 | 2 (4 Battleline) |
| Strike Force | 2,000 pts | 3 DP | 4 | 3 (6 Battleline) |
Each detachment costs 1–3 DP. Battleline units can be taken in double the usual copies.
Every 11th Edition Change, In One Place
The complete changelog from 10th to 11th Edition. All of it is reflected in GrimSlate's rules library, validation, and the How to Play guide.
Army Building
- Detachmentsexactly oneDP budget
Spend 2-3 Detachment Points across one or more detachments (full table above).
- Enhancement limit3 flat2 / 4 by size
2 at Incursion (1,000 pts), 4 at Strike Force (2,000 pts).
- Upgrade enhancementsNew
A new Upgrade tag: apply one enhancement to up to 3 non-Character units — it counts as a single enhancement choice.
- Battleline
Battleline units can be taken in double the normal number of copies.
Shooting & Cover
- Benefit of Cover+1 armour save-1 to hit
Cover now degrades the attacker's hit roll — it finally works against invulnerable-save units.
- HiddenNew
Infantry, Beasts, and Swarms in cover that didn't shoot last turn can't be targeted beyond 15".
- Engagement range1"2"
- Psychic weaponsNew
Psychic weapons ignore modifiers to BS, WS, and the hit roll.
Saves & Rolling
- Invulnerable saveschoose one saveone roll, two checks
One save roll is checked against unmodified InSv, then against armour after AP — never two separate saves.
- Fast rollingNew
The defender orders their models before saves are rolled, so casualties are predictable.
Characters
- Leader & Support rolesad-hoc double-attach1 Leader + 1 Support
Characters are designated Leader or Support when joining a unit — one of each allowed.
- Attachment timing
Character-to-unit assignments happen during list construction, not at game start.
- Persisting abilitiesNew
Leader abilities keep working even after the attached squad is destroyed.
Movement & Reserves
- Unit coherency2" + 9"
Within 2" of at least one other model and 9" of every model in the unit.
- Flying units-2" move
Fly costs 2" of maximum movement but ignores vertical distance.
- Reserves arrival9" from enemies8"
Charges out of reserves still need a 9" roll.
- Battle-shock
Test in your own Command Phase to remove it — even while above half strength.
Charges & the Fight Phase
- Charge sequencepick targets, then rollroll first
Roll 2D6 charge distance before selecting targets; move base-to-base when possible.
- Overrun FightNew
If your charge target is destroyed before you activate, make a 3" pile-in toward another unit.
- Fight phase structure
All pile-ins happen at the start of the phase, consolidations at the end, with fully alternating activations.
Stratagems & Command
- Stratagem limitstackable1 per unit per phase
Each unit can only be affected by one stratagem per phase — Command Re-Roll included.
Missions & Objectives
- Objective markersprinted markersterrain pieces
Objectives are now physical terrain pieces on the battlefield.
- Force DispositionsNew
Five mission types (Take and Hold, Disruption, Purge the Foe, Priority Assets, Reconnaissance) — each army plays its own primary objective, granted by its detachments.
- Battle rounds
Games are still 5 battle rounds. Crusade content moves out of codexes.
Existing Lists Update Automatically
Open a saved list or import an older backup and GrimSlate normalizes it before the editor or cloud sync can use it:
- Stable unit and faction identity resolution
- Current unit and enhancement points
- Automatic detachment and validation updates
- Unresolved entries preserved with a repair issue
Safe by default
Migration is idempotent and keeps the original snapshot until the normalized roster has been validated. A legacy cloud copy cannot overwrite a newer-schema local list.
If an old unit cannot be matched unambiguously, it remains visible with zero current points and a repair issue instead of disappearing silently.
11th Edition FAQ
Does GrimSlate support Warhammer 40K 11th Edition?
Yes. GrimSlate is fully migrated to 11th Edition: the Detachment Points system, all new and updated detachments with full rules, updated points from the online Munitorum Field Manual, Leader/Support characters, and 11th Edition army validation. New army lists use 11th Edition by default.
What happens to my 10th Edition rosters?
They are updated automatically when loaded. GrimSlate preserves unresolved entries for repair, replaces obsolete points with current data, and saves the normalized roster after validation.
What are Detachment Points in 11th Edition?
Detachment Points (DP) are the new army-building currency. Instead of picking exactly one detachment, you spend a DP budget: 2 DP at Incursion (1,000 pts) and 3 DP at Strike Force (2,000 pts). Each detachment costs 1-3 DP, so you can take one powerful 3 DP detachment or combine two or three cheaper ones — as long as no two share the same Unique Tag.
Are 10th Edition codexes still valid in 11th Edition?
Yes. Games Workshop confirmed all 10th Edition codex datasheets remain valid at 11th Edition launch. What changed is points (new Munitorum Field Manual), the detachment system (Detachment Points), army-building limits, and the Leader/Support character system — all of which GrimSlate handles for you.
Is GrimSlate's 11th Edition army builder free?
Yes — completely free, web-based, and with no download required. All factions, detachments, points tracking, validation, and exports are free for every player.
