Secrets (8)

Claim the northern hemisphere by digging south for gold, avoiding areas '1', '2', and '3', and leaving the rightmost section of the western gold to avoid early attacks. Ignore the graveyard for now and focus on the gold in the far NE corner. Dig to the gems by excavating only the gold against the impenetrable rock for infinite funding.

Build essential rooms, research the Torture Chamber, and create Dark Mistresses. Consider Trolls and Bile Demons for sacrificing into a Horned Reaper. Recruit the Mistress(5) hiding east of '1' between gold and rock.

After researching the Guard Post, defeat the group at '1', claim the southern gold, and build guard posts along the waterline to prevent attracting hostile Tentacles and Samurai. Dig west to find 2 Hellhounds(4) for manufacturing. Be cautious when going for the "Increase Level" special between '1' and the Mistress, as it is trapped with Poison and Boulder traps.

After digging into the lake and warding it with Guard Posts and a locked door, train your creatures and fight through the hero fortress to connect to the blue Keeper's land by claiming all tiles in the hero dungeon.

Cast maximum powered "Invisibility" and "Speed" on an Imp, place it outside your main dungeon, and possess it.

Quickly walk around the vicinity and dig into the blue Keeper's domain on the other side of the lake, between the two sections of solid rock, before the area is fortified. This will cause stealth to be lost upon digging.

Once a connection is made, pull back and break through the earth at section '15' to release 2 more Giants(10).

To ensure the blue Keeper's destruction, release all Heroes in the southern part points '14' to '16'. Wait for the Samurai to enter the blue dungeon, then return with your Imp to that section and set them free.
