How to mine

Find a lobby with steady 19 to 20 TPS, little structure grief and a day count under 10. To see the day count, press F3 + F6 and set day_count to “Always”.

Load a route and dig to it. At each waypoint, place a Cobblestone, aim at it and throw a Bob-omb. Once every waypoint is done, turn off all Heat Resistance sources, stand in lava until you reach about 95 Heat, then turn them back on.

Stay near 95 Heat the whole time. If it climbs too high, drink a Water Bottle, kill a Yog or jump a few times. Heat Resistance comes from Keep It Cool, Blazing equipment, Armor of Divan, the Bal pet, the Yog Membrane attribute and mining deployables.

Mine each vein fully, then Etherwarp to the next. Use your ability as soon as it is ready. Ping gliding helps a lot: move to the next block before the last one breaks, to make up for your ping. The ping-offset-miner mod shows when to do it.

Drill swapping

Since update 0.27.2, Mining Speed Boost updates your stats while it runs, so drill swapping only works with two Divan’s Drills. Do not drill swap for Magma Fields gemstones. The ability also ends early if you swap to an item without a Blue Cheese omelette in its last 5 seconds.

Ruby

Run two 30-minute tests to see whether Maniac Miner or Mining Speed Boost earns more for you. If Maniac Miner wins, keep drill swapping with the Maniac Miner tree. If Mining Speed Boost wins, put the Sunny Side omelette on the main drill and stop swapping. A Royal Pendant of Divan gives just enough Mining Speed to break Ruby in 6 ticks.

Breaking Power 7 gemstones

Use the Sunny Side omelette on the main drill if you reach the 4-tick threshold with a level 2 Mining Speed Boost (+250% instead of +300%). Otherwise keep Blue Cheese on the main drill.

Routes

Example routes for each gemstone, in SkyHanni and Coleweight format, are shared in the Mining Cult Discord along with more in the route-sharing channel. Each route lists where to place mining deployables and where to bridge between waypoints.

Gemstone Veins Deployable waypoints
Ruby 53 1, 29
Amber 48 1, 11, 21, 33, 43
Sapphire 39 1, 16, 25, 37
Jade 35 1, 9, 16, 25, 35
Amethyst 38 1, 11, 21, 36
Topaz 27 1

Useful mods

  • SkyHanni for quality of life (and routes).
  • Waypointer for routes.
  • SkyblockCollectionTracker for rates, the ability timer and a stat overlay.
  • ping-offset-miner for ping gliding and an efficiency display.
  • NoFrills for quality of life and a drill fuel fix.
