When you return to Guild Idle after being away, the game simulates the time elapsed — processing dungeon runs, floor-by-floor combat, item drops, gold and XP gains, and run completions. The simulation uses the same combat logic as live play; it is not an approximation.
Default Time Cap
Without upgrades, Guild Idle simulates up to 4 hours of offline progress. Time beyond this cap is not simulated.
Eternal Vigil Upgrades
The Eternal Vigil upgrade in the Honor Store extends this cap by +1 hour per level, across 8 levels (costs rise from 200 to 32,000 Honor):

What the Simulation Covers
All active dungeon runs (floor progression, combat, kills)
Item drops and gold/XP awards
Run completions and automatic restart cycles
Consumable drops on floor clears
Codex discovery from new item drops
What's Excluded
Manual actions (equipping items, spending upgrades, starting new runs)
Eternal Strife runs (paused offline — heroes can't die while you're away)
Colosseum matches (require active play)
Raid attempts (require active dispatch)
Tip: Maximise offline efficiency by ensuring all party slots are running dungeons before closing the game. Longer dungeons (more floors) give more gold per cycle.
