d) "RECRUITS" - Nasreem

Break into the first accessible rock formation to release two creatures. Build a lair nearby to house them.

Mine the nearby gem seam to build up cash. There are gem seams in the four corners of the circular rooms around your dungeon heart.

Consider turning every strip of path around the dungeon heart into a treasury to store up to 180,000 gold.

Mine out small rooms as they become available and build new rooms, including a Prison and Torture Chamber.

Excavate in the southern area to find cannons in the southeast and southwest. Build wooden bridges over them, have your creatures destroy the bridges, and excavate behind them to find Level Up specials.

Excavate directly east and west to find two Level Up specials in the water. Build wooden bridges to collect them and save them for when you have 20 creatures to level up.

Use skeletons to disable Fear Traps to the south for access to another special.

Excavate and claim two massive treasure rooms; sell them and convert them into a Graveyard and a larger Library or Training Room.

Excavate North around the Hero gate to find more specials.

To reach 24 creatures, trigger a hero invasion or pick up creatures from the Hero pit and drop them into your dungeon. Imprison them to turn them into skeletons or use them to create new Vampires.
