Purity, Limitless and Endless War

Endless War removes the final boss and continues enemy cycles. Limitless changes the late upgrade pool after ordinary upgrades run out. Purity enforces equipment limits. These are separate mission options; unlocking one does not activate the others.

Mode effects

Option	Main change
Fast Attack	Mission timer runs at double speed, with increased Veterancy
‘Eavy Metal	Faster champions and enemies, with projectile/coin bonuses
Grim Darkness	Stronger enemies whose health and movement pressure grow over time
Endless War	Repeating, harder enemy cycles instead of the final boss
Limitless	Separate stat bonuses after ordinary upgrades are exhausted
Purity	Strict weapon and passive limits

The database’s mission-option records keep these rules separate from character or passive effects. Mode names are not ordinary difficulty tiers with a published universal win-rate order.

Relic gates

Purity uses Standard of the Emperor Ascendant in 40K or Oathstone in Age of Sigmar. Fast Attack is connected to the Gyrotemporal Vault on the 40K side. The Tarot and Arcana options require their respective deck relics.

A locked option is a progression task. Merely selecting a stage whose screenshot shows that mode does not replace collecting the required relic in your own save. Map relics distinguishes the information tools used for hidden objects and rescue markers.

Stage pickups under Purity

Stage items can depend on an unlock, scanner, map variant or chance check before they appear. Picking one up is a separate equipment-limit question. With Purity enforcing the limits, do not plan a route on the assumption that a stage pickup always grants an extra slot beyond the selected cap.

This affects passive planning: an evolution companion found on the ground still needs to be obtainable under the run’s current conditions.

Fast Attack and objective time

A double-speed mission timer changes how quickly its displayed time advances. It is not the same as a promise that every movement, enemy attack and item collection takes half the real time. Read the timer condition for a survival objective rather than using the length of an edited video as its completion proof.

Endless and Limitless together

A long-running enemy cycle can leave all normal equipment maxed. Limitless can then supply its own available bonuses if it is unlocked and enabled. Endless alone does not guarantee that bonus menu, and Limitless alone does not remove the final boss.

Level-up choices explains the exhausted-pool condition. Keep those options fixed when comparing two weapon builds or the effect of a permanent enhancement.

For Max Mahon’s 1,000-Nurgling objective, the Maelstrom Key on Imperial Shipyard opens the 40K Endless War option for a longer attempt.
