This guide was created to help people obtain this achievement using strategies that decrease the time it takes to mine 100 million gold. Since the 2.03 patch, this achievement seems to be working again. I have updated this guide with the easier strategy to unlock the achievement.

Some users have reported that these strategies may no longer work or are very slow. If they don't work for you, try the strategy posted by Lycrus at the end of the guide.

If any of these strategies work for you, please rate my guide and let me know. I appreciate all feedback and suggestions.

This achievement is tedious to unlock if done just by playing the game, however the following strategies will help keep your sanity. I created the first strategy as a modified version of other strategies created by other players over the years. The second and third strategies are other methods that could be used as well but are less effective. Previous strategies by other players aren't possible now due to game changes and patches/updates.

There are a few things to note for this achievement:

• It can only be done on official maps (so workshop maps / map editor won't work; there are some maps on the workshop for this achievement but they will not work)
  
• Only gold mined by normal imps count (so gold mined by spirit workers doesn't count nor does gold consumed by the colossus count)
  
• Gold from other sources does not count (artefacts, rituals, etc)
  
• Gold mined must be stored in a vault for the counter to increase (so just the act of mining gold doesn't increase the counter)
  
• Map mutators do not work.
  
• Godmode does not work.

Checking Progress: You can check how much gold you have gained by using the debug console (press scroll-lock to show/hide the debug console), however it only updates when the game first starts.

Strategy: we use the last my pet dungeon level (Hell's Deep?) and complete all the objects. Then we mine the gold shrines (6 in total, including the enemy bases). We fill the map with vaults and build a midas door near the toybox gateway to the north. We drop some enemies behind the door and let them drain our vaults while our workers mine the shrines which replenishes our vaults. You can AFK while this occurs but it won't take too long.

For this guide, we will be using the My Pet Dungeon level: Hell's Deep. Play the map normally and do not enable godmode or mutators. Consider turning on autosave in the game settings menu and setting it for 10 minutes, or use quicksave every few minutes - incase you crash!


Step 1: Complete all level objectives including destroying the enemy dungeon hearts. Dig out the entire map. Clear a path to the gateway spawner. I recommend getting at least 75,000 points because a pop-up appears that pauses the game, and we don't want that to appear while we are afk farming!

Step 2: Click on your gateway and disable every minion from spawning. Drop your minions into the gateway so you have no minions.

Step 3: Build a large vault somewhere (not too big or the map will lag) - 17x17 will be enough. Also build some gold vortexes near each gold shrine. Build a midas door in the single tile near the toybox gateway (next to the sand tile). You can use the forge spell to complete it. Lock/close the midas door. Activate each gold shrine and make sure you have only normal workers on them (no spirit workers since they don't contribute to the achievement).

Step 4: Set the game speed to 150% (in the game settings menu).

Step 5: Save. We save just in case so we don't have to do the above all over again if we crash.

Step 6: Set the toybox level to 10 and pick up some of the enemy units. Drop them on the toybox gateway or nearby but behind the midas door. They will begin attacking the door and draining your gold. You want to drop them 1 at a time and try to find a balance so your workers are mining slightly more gold than the enemies are draining by attacking the door.

Step 7: AFK for 15-30 minutes (not sure exact time, but not more than an hour). You should have mined enough gold to get the achievement.

Step 8: If you don't get the achievement, try exiting the game and restarting, then press scroll-lock to see how much gold you've mined. You'll need 100,000,000 to get the achievement.

I did not create this strategy, however I am posting it here in case the previous two did not work for you. There is a video guide available which was created prior to 2.0 and I will post it below when I find it.

Strategy: Play a map with lots of goldshrines (ie. skirmish map). Play against a weak computer player but don't kill them, instead box their dungeon heart in with walls and well of souls to kill the workers (or with 2.0, just use the lightning defense without walls to zap workers). Then AFK while your workers mine the gold shrines. Un-afk, build gold vortex and vaults, save, reload, repeat.

Step 1: Play the game normally and defeat all the AI's units, then block them over with walls and well of souls, or use the lightning defense without walls to kill the workers that spawn at the enemy dungeon heart. Make sure not to kill the heart with your defenses/units.

Step 2: Dig out the rest of the map and capture all the gold shrines, but don't mine them yet. Click your gateways and disable all units from spawning.

Step 3: Rally all your units to a gold shrine and delete the rooms/vaults. Cast blood gold on all your units (can easily be done from the unit ui screen while holding ctrl and clicking the units portraits). Once they are all gold statues, have your workers mine them until they are all gold piles.

Step 4: Activate your gold shrines and make sure you have enough workers to mine each one. While it may be a bug (and could be fixed after writing this guide), build conduits next to gold shrines to make the workers mine them faster. Since you have no vaults, the workers will mine the shrine and drop the gold pile at their feet.

Step 5: Save. We save just in case so we don't have to do the above all over again if we crash.

Step 6: AFK a long time (ie. 2+ hours). Make sure autosave is on incase the game crashes.

Step 7: When you think you have enough gold piles, save the game.

Step 8: Turn off the gold shrines. At each shrine, build some gold vortexes, then build a 3x3 box with the center tile empty somewhere on the map like we've done in the previous strategies. Put all your workers in this box once the gold vortexes are built. If you have extra mana, summon more workers inside the box.

Step 9: Fill the map with vaults. If you run out of money, pick up some of the gold piles and drop them on your dungeon heart / vaults.

Step 10: Save the game as a new file. We will use this save file to reload multiple times. Ideally you want to save the game while the 3x3 box of workers is in view to make reloading faster/easier.

Step 11: Dig one of the walls out of the 3x3 box (or use the annex spell). The workers will escape and run to the nearest gold shrine, deposit all the gold piles into the gold vortexes and then go to the next shrine. Once all the vaults are full, reload and do it again.

Step 12: Similar to the gold removal strategies in the strategy above, you can use sentinels to reduce the gold in your vaults (via combat or payday) so you don't have to reload as often. One option is to let the enemy ai takeover a gateway and start spawning minions, then put your sentinel on the gateway or lair and have them fight the units. You can heal the sentinel with the give gold spell. However this strategy can be risky because the sentinel might wander off and destroy the dungeon heart if you aren't paying attention.

From Lycrus:
For everyone else who comes here to somehow get this achievement: The shrine method doesn't work anymore, the other methods neither. Mining gold statues works but is incredibly tedious and time-consuming.

FOR SOME REASON if you play in Oberans Home realm in the campaign...the gold-mined magically adds up. I have no idea how this exactly works, but what i did was:

Go to oberons home realm. Combine 2 more achievements: Stay a while and listen and the 5 hour home realm one. Build out the entire realm, make some cool dungeons. Towards the end, build high expensive rooms, mine gold from the gold-block. build more vaults/rooms, mine again. Save and quit. Load the level. sell a room, build a room, mine the block.

At first it started adding around 1 million to mined gold. then 2..then 6...later on a save and load just magically added another 10million gold to the achievement.

No idea what triggers it, but it works and makes it super easy to get the achievement.
