World Eaters: rules coverage (2026-10-02)

T-541, the first batch of T-542 (Jordan, 2 Oct, before sleeping: "add all special rules to units, all detachment rules, at the very least"). Made by node tools/coverage.js --faction "Chaos - World Eaters" from docs/data/unitfx.json, leaderfx.json, detfx.json and armyfx.json; each ability read on Wahapedia's 11th-edition pages and written in our own words. A report: the calculator reads the dice effects (units' own behind flags.json's "unitfx"); nothing here changes a published score or letter.

Statuses. Modelled: the dice effect is all of it. Partly: some of it is dice, the rest noted. Noted: nothing for the dice; where it would be, can't yet says what the engine lacks. Unread: not in our data yet. An effect that starts off in the calculator (a damaged bracket, a rare condition) is marked so; the player switches it on.

Totals

A datasheet counts as modelled when every ability on it is dice, partly when some are, noted when none are.

What's here. Every World Eaters datasheet in BSData's catalogue at our commit (the six Crucible characters aside), read against Wahapedia's 11th-edition page on 2 Oct, and the 8 detachments. Blessings of Khorne, the army rule, is in armyfx.json as partly: a pick of the round's blessings among the three that are dice (Martial Excellence: Sustained Hits 1; Warp Blades: Lethal Hits; Decapitating Strikes: Devastating Wounds against infantry), alone or in pairs. The eight-dice roll that buys them isn't in the maths, and neither are the three movement and fight-on blessings. Pact of Blood is noted.

Decided alone.

• 29 datasheets that the World Eaters share with the Chaos Space Marines or the Death Guard (Legends tanks and flyers, the Land Raider), with the same abilities by name, are copied from those armies' entries, which were read for them. Khorne Berzerkers are written from the World Eaters page, not copied.
• "Terror of Khorne", which BSData lists on the daemon engines, is Brazen Engines' detachment rule (a Battle-shock test at -1 for an engaged enemy) and is noted as that.
• Angron's three Wrathful Presence abilities are now one pick; Driven by Ultimate Rage keeps its effect (ignore hit modifiers in melee). Skarbrand's damaged profile adds Attacks instead of taking hits away, so it's written as +2 Attacks, switched off, and not as the usual -1 to hit.
• Conditional bonuses start off: Savage Exaltation (target below strength), Beacons of Rage's +1 to wound (target below half), the Predator Destructor's suppression, the Slaughterbound's once-a-battle Possessed Lord.

What the army needs next. The Blessings of Khorne roll (eight dice, doubles and triples), so the blessings follow the dice. Then fighting after being slain (Total Carnage) and fighting again (the Helbrute's Frenzy), and Cleave.

Vocabulary gaps, by how many units need each

What the engine would need to model the rest, from each rule's can't yet and kind; a unit counts once per gap.
