The imp cache is an adventure map location, and commonly known as one of the creature banks. It is guarded by 100-300 imps divided into five stacks, one of which may be a stack of familiars. The more guards there are, the better the reward. The treasure contains 1000-3000 and 2-6 .
The guards are divided into five stacks of 20/30/40/60 Imps (red hexes). 50% probability of getting a stack of Familiars in the left lower corner (C hex). All the guard stacks with the same speed are attacking in alphabetic order from A to E.
The hero's troops are located in blue hexes 1-7 (a tail hex for two-hexed creatures) accordingly to stack positioning in the army. But if the hero has less than 7 stacks, e.g. 3, they will be placed in hexes 1-3 no matter how they were placed in the army.
Slain enemies do not respawn (should the hero retreat or be defeated).
