AFK Mine

Doing nothing is the whole point of the AFK Mine. You enter through the small island on the north-eastern side of Moosewood, where Cole is the resident NPC, and you can stay away from the keyboard for as long as you like while rewards, XP included, keep coming; since update 1.28.0 the XP is passive. There is a catch: since update 1.26.3 you need a second island besides Moosewood unlocked before the mine opens. You cannot interact with the area itself, only look at an image of Cole holding a pickaxe.

Luck sets the quality of what drops. Roblox Premium adds +50%, each friend adds +10% up to 50%, and free AFK luck adds +10% every 15 minutes up to 50%. Stack all three and you reach 150%; a free player tops out at 100%.

The reward table is mostly titles and baits. Nothing (listed as Trash) is the single most common result at 20%, then 5-150C$, Timely Fisherman and Clock Lobster at 12.75% each. At the bottom, five rewards share the 0.05% floor: the title The Final Fishness, 1000 Year Old Wood, Timeless Threading, the Exotic Golden Worm bait and the Hourglass Lantern, which the wiki says currently serves no purpose. Every 16 minutes or so the server rejoins everyone, and earlier rewards are kept.
