AFK leveling: leave the fight running
Map → leave → claim. That is the Idle muRPG loop.
What accumulates
The server keeps your character in combat on the map you last set. Experience, gold, and drops stack until you claim them. You do not need the tab open. If the zone is too hard, you come back to a thin bag and a lesson. Pick a map you finish.
Before you lock the phone
Wear the set that actually lives through the pack. Spend points you have been hoarding. If you have a timed buff, pop it. Then leave. A two-minute prep beats eight hours on the wrong floor. Gear names live in the item list.
Overnight vs. a few hours
A commute farm is the usual cycle. Overnight works if the map does not wipe you. You are not expected to sit in combat. Come back, claim, decide if the floor still makes sense. Phone check-ins are covered on mobile.
When you sit down
Claim. Sort. Push a boss or a ranking check if you have the stomach. Then park again. Systems around it: classes and rankings. Play from the home page.
