Starting your run, teleport to the Lava Maze with 28 muddy keys in your inventory, and 30 keys in your pack yak, along with a ring of Wealth equipped. Enter the maze, slashing the webs apart and avoiding the black knights and hill giants, and make your way to the muddy chest at the end. Avoid the lesser demons inside the muddy chest area if they are aggressive. When finished, return through the maze. Run to the nearest cape seller to the west of the Lava Maze and refill your yak and inventory with keys using a preset. Sometimes a roaming banker will be within sight when you leave the maze so use this bank when possible.
Be wary as your first used key can drop items on the floor. Use Bladed dive with mobile to optimise your running time.

Make your way to the Lava Maze either (by running, using teleports or using the canoe) with 28 muddy keys. If you can use a Beast of Burden this will increase your GP/hour.
Slash the webs apart and avoid the black knights and hill giants, and make your way to the muddy chest at the end. Avoid the lesser demons inside the muddy chest area if they are aggressive. Run to the nearest cape seller/ banker to the west of the Lava Maze and refill your inventory with keys using a preset. Sometimes a roaming banker will be within sight when you leave the maze so use this bank when possible.
Be wary as your first used key can drop items on the floor. Use Surge (with mobile) if you have them to optimise your running time. Players will have no problems making 10 trips per hour if using surge and this is possible if paying close attention without it. When finished, you will have to navigate the wilderness to level 20 before you can teleport out.

Located in the centre of the Lava Maze, the muddy chest contains various rewards. Opening it consumes a muddy key. It is the free-to-play version of a Crystal chest.

Muddy keys have a buying limit of 100 on the Grand Exchange, but they are relatively easy to buy since they have a high trade volume.
