The whole app has been migrated — data, rules, validation, exports, and guides. Here's what that means for your army building.
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.
All ~300 new and updated detachments from the official Faction Packs — with full detachment rules, stratagems, and enhancements for every faction.
Unit and enhancement points for all factions follow the official online Munitorum Field Manual, including the day-one 11th Edition points changes.
Characters are now designated Leader or Support when joining units — one of each per unit. GrimSlate uses official attachment data and validates it automatically.
Enhancement limits (2 at Incursion, 4 at Strike Force), duplicate limits, doubled Battleline allowance, DP budget, Upgrade enhancements — all enforced as you build.
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.
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.
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.
Spend 2-3 Detachment Points across one or more detachments (full table above).
2 at Incursion (1,000 pts), 4 at Strike Force (2,000 pts).
A new Upgrade tag: apply one enhancement to up to 3 non-Character units — it counts as a single enhancement choice.
Battleline units can be taken in double the normal number of copies.
Cover now degrades the attacker's hit roll — it finally works against invulnerable-save units.
Infantry, Beasts, and Swarms in cover that didn't shoot last turn can't be targeted beyond 15".
Psychic weapons ignore modifiers to BS, WS, and the hit roll.
The invulnerable save is checked first, then the armour save — no more choosing.
The defender orders their models before saves are rolled, so casualties are predictable.
Characters are designated Leader or Support when joining a unit — one of each allowed.
Character-to-unit assignments happen during list construction, not at game start.
Leader abilities keep working even after the attached squad is destroyed.
Within 2" of at least one other model and 9" of every model in the unit.
Fly costs 2" of maximum movement but ignores vertical distance.
Charges out of reserves still need a 9" roll.
Test in your own Command Phase to remove it — even while above half strength.
Roll 2D6 charge distance before selecting targets; move base-to-base when possible.
If your charge target is destroyed before you activate, make a 3" pile-in toward another unit.
All pile-ins happen at the start of the phase, consolidations at the end, with fully alternating activations.
Each unit can only be affected by one stratagem per phase — Command Re-Roll included.
Objectives are now physical terrain pieces on the battlefield.
Five mission types (Take and Hold, Disruption, Purge the Foe, Priority Assets, Reconnaissance) — each army plays its own primary objective, granted by its detachments.
Games are still 5 battle rounds. Crusade content moves out of codexes.
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:
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.
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.
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.
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.
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.
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.
