The Warhammer 40K 11th Edition Army Builder

GrimSlate is fully migrated to 11th Edition: Detachment Points, every new detachment with full rules, updated points for all factions, and a one-click converter for your 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 Builder

Combine multiple detachments under a DP budget — 2 DP at Incursion, 3 DP at Strike Force. Live budget tracking, Unique Tag conflict detection, and per-detachment DP costs.

Every 11th Edition Detachment

All ~300 new and updated detachments from the official Faction Packs — with full detachment rules, stratagems, and enhancements for every faction.

Points Synced with the Official MFM

Unit and enhancement points for all factions follow the official online Munitorum Field Manual, including the day-one 11th Edition points changes.

Leader & Support Characters

Characters are now designated Leader or Support when joining units — one of each per unit. GrimSlate uses official attachment data and validates it automatically.

11th Edition Validation

Enhancement limits (2 at Incursion, 4 at Strike Force), duplicate limits, doubled Battleline allowance, DP budget, Upgrade enhancements — all enforced as you build.

One-Click Roster Converter

Convert any 10th Edition roster to 11th with a full before/after points diff, instant revalidation, and the option to keep a 10th Edition copy.

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 SizePointsDP BudgetEnhancementsUnit Copies
Incursion1,000 pts2 DP22 (4 Battleline)
Strike Force2,000 pts3 DP43 (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 savesoptionalmandatory, first

    The invulnerable save is checked first, then the armour save — no more choosing.

  • 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.

Already Have 10th Edition Lists?

Your existing rosters are untouched — they keep their 10th Edition data, points, and validation. When you're ready to make the jump, the converter does the heavy lifting:

  • Per-unit before/after points comparison
  • Enhancement cost updates from the new MFM
  • Instant revalidation with 11th Edition rules
  • Option to keep a 10th Edition copy of your list

Nothing is lost

Conversion is always opt-in and always previewed. You see every point change before confirming, and units without 11th Edition rules (Legends) are clearly flagged so you can decide what to do with them.

Prefer to stay on 10th for a league or campaign? Your 10th Edition rosters remain fully editable with their original data for as long as you need them.

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 rosters are built for 11th Edition by default.

What happens to my 10th Edition rosters?

Nothing — they keep working exactly as before, with their original 10th Edition data and validation. When you're ready, every 10th Edition roster has a 'Convert to 11th' button that shows a full before/after points comparison and lets you keep a 10th Edition copy.

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, all detachments, points tracking, validation, exports, and the roster converter are free for every player.
