- Invade Lord Darius's Keep and slay him
- Build a Library and use the Warlocks to research new spells
- Train up your creatures in the Training Room
The Map starts with the Dungeon Heart surrounded by walls, the Library and Training Room will be made available to build. The first thing is to build a 5x3 Lair and a 3x3 Hatchery, then claim the Portal nearby.
After building all the rooms, place the Goblins in the Training Room and let Warlocks research spells in the Library, but be wary as soon heroic Dwarves will break in the dungeon and assault it, but the Goblins will deal with them without too many problems. Afterwards, you can dig north where there will be a small area surrounded by water and a few veins of gold, since no Bridges or Treasuries can be built it's recommended to dig the veins moderately.
Nearby before Darius' keep there's a Special Mana Boost, useful to use in case the mana is running low. The mentor now should tell about digging the two areas of land that lead to Darius' keep, be prepared, as soon it's breached, a wave of Dwarves will attack, soon joined by Lord Darius, if fully trained Goblins and Warlocks will make short work of the Dwarves and using the Thunderbolt spell to stun Darius will make things easier to the creatures to kill him. Once killed, Horny will come to claim the Portal Gem
