These Items were introduced in The Quests Update: A Cold Start on December 5, 2024 without an active use. On May 21, 2026, they became usable to cool Relay Bays and slow heat buildup.
Relay bay cards now show clear timing and state info: remaining overclock time, cooldown end, and how long active DX Coolant will last on that bay.
DX Coolant can be active per bay (you can run coolant on mint and refinery at the same time), and the heat readout is now next to the bay name consistently on desktop and mobile.
Heat is the new throttle. Bays generate heat while they run. You manage it with bay modes and DX Coolant.
Items are grouped into four categories: Raw, Crafted, Gear, and Consumable. Some items are explicitly excluded from refine list (boosts, bounties, DX Coolant, rare loot).
Daily Refined: the top 10 split a DX Coolant ladder (1 up to 10 coolants, 55 total) plus a 666-Salvage lottery.
DX Coolant drops at every quest level 25, scaling from 1 up to 10 per claim.
