Warhost of Duality is the aggressive, combat-oriented Lumineth formation for AoS 4th edition. It rewards a list built around elite infantry and cavalry that want to strike decisively. Exact ability wording (reported as a "Strike as One"-style effect) should be confirmed in your current battletome, as details can shift with errata.
What the formation does
It enhances the army's melee alternation, letting you pick two friendly units to fight in sequence rather than one when it is your turn to choose. Combined with the army's Lightning Reactions trait, this lets you chain a burst of combats and remove priority targets before your opponent can trade back.
Who it suits
Players who want a proactive, melee-led Lumineth army rather than a shooting or spell-spam build. It suits elite infantry and cavalry cores and players comfortable with careful fight-phase sequencing and target priority.
Key units
- Vanari Bladelords and Bannerblade as dedicated melee elites
- Vanari Auralan Wardens as a counter-charging anvil
- Vanari Dawnriders for flanking and follow-up hits
- Alarith Stoneguard as a durable hammer when buffed
- A supporting hero such as the Vanari Lord-Regent to enable rallying and buffs
When to pick it
Choose it when your list is built to win the combat phase and you want to maximise the alternating-fight advantage. It is less useful for shooting-heavy or pure-caster lists that avoid melee. Confirm current wording and any restrictions before relying on the two-unit fight sequence.
Common questions
How does this stack with Lightning Reactions?
Both push the same idea: picking extra units to fight in sequence. Together they let you concentrate combats to delete a key target early, but check the current rules for exactly how the effects interact and whether any limits apply.
Is this a shooting formation?
No. It is built around the melee phase. If your plan centres on Sentinels, the Starshard Ballista or spell damage, one of the other formations will usually serve you better.
