The GrimSlate analysis view: a written read, a capability radar, and eight percentile bars

Eight Capabilities, One Shape

Every unit in your roster is run against a set of standard target archetypes using its actual weapon profiles, abilities and loadout. The result is eight scores — and the shape they make is your army.

Anti-armour
Expected damage against a heavy target — high Toughness, good save, plenty of wounds.
Anti-infantry
Output against line infantry: the bodies that hold the middle of the table.
Anti-horde
How well the list clears cheap, numerous chaff before it swamps an objective.
Anti-elite
Damage into tough multi-wound models with invulnerable saves.
Objective control
The OC your army actually puts on the table, weighted by what survives to hold it.
Resilience
How much effort it takes to remove your models, per point you spent on them.
Mobility
Movement, Advance and charge threat across the whole list, not just your fastest unit.
Reach
How far the list can hurt something on turn one without moving into danger.

More Than a Score

A number on its own is not advice. Every part of the page says what it means and which units produced it.

The read
One written verdict at the top of the page: the capability your list is best at, the one it is worst at, and the unit carrying each. If you only look at one thing, look at this.
Battle readiness
Four questions a plan has to answer — threat coverage, mission scoring, delivery and reserves, staying power — each answered with numbers from your own roster, and a warning when one unit carries a capability on its own.
Matchup lens
The same eight axes, re-weighted for the army in front of you: horde, line infantry, elite, armour or mixed. It shows which axes carry the result, never a predicted winner.
Secondary mission fit
Every mission card read against your list's shape and grouped into what it scores easily, what it can attempt, and what will be hard.
The units behind every number
Open any axis and see exactly which units produce the score, and what share of it each one contributes. No number on the page is a black box.
Exact values and assumptions
A table with the raw per-100-points figures behind every axis, and a panel spelling out every assumption the maths makes — including what it deliberately does not model.

From List to Read in One Click

No exports, no spreadsheets, no setup. The analysis reads the list you already built.

01

Build or open a list

Any roster in GrimSlate works. Nothing to configure, nothing to export — the analysis reads the wargear you already chose.

02

Open the Analysis view

From the list, switch to Analysis. Every axis, the read and the readiness cards are computed in your browser, instantly.

03

Find the hole and fix it

Swap a unit, change a loadout, come back. The numbers move with your list, so you can see whether the change actually helped.

What It Is Not

It is not a win prediction, and it will never claim a matchup is won. The percentiles compare the shape of your list against 6,800 generated reference lists — 200 per faction, built from the same datasheets you build from — not against tournament results.

Terrain, mission scoring, stratagems, target priority and the person on the other side of the table decide games, and none of them are modelled. What the analysis does is answer a narrower question honestly: given the weapons in this list, what can it do — and what can it not?

Common Questions

Does GrimSlate tell me if my Warhammer 40K list is good?

It tells you what your list can do. GrimSlate scores eight capabilities from the real weapon profiles in your roster — anti-armour, anti-infantry, anti-horde, anti-elite, objective control, resilience, mobility and reach — and shows each as a percentile against a reference population. That reveals strengths and holes in the list's shape. It is not a win prediction: terrain, mission scoring, stratagems, and target priority are not modelled.

Where do the percentiles come from?

From 6,800 generated reference lists — 200 per faction, built from the same datasheets and points you build from, at 2,000 points. Your list is scored with the identical formula and placed against that population. So «top 10% for anti-armour» means your list beats roughly 90% of those reference lists on that axis. It is not tournament data.

Is the analysis free?

Yes. List analysis is free for every list, with no account required and no premium tier. It runs in your browser.

Can I analyse someone else's army list?

Yes. Every publicly shared list on GrimSlate has the same Analysis tab, so you can read a community list's strengths and weaknesses before copying it into your own collection.

How is this different from a damage calculator?

A damage calculator answers one question at a time: this unit, into that target. The analysis runs that maths across your entire list against a set of standard target archetypes, then compares the totals to other lists. Use the calculator for a single fight, the analysis for the whole army.

Which editions are supported?

The analysis reads whichever edition your roster uses, including current 11th Edition points and detachment rules, and it accounts for the army and detachment rules that change the maths.

What Does Your List Actually Do?
