Combat Points

Combat Points were a currency in Dungeon Keeper, earned by raiding enemy Keepers.
They were used to upgrade your Dungeon Heart up until level 10 and to recruit certain Immortals.
==Earning Combat Points==
You could earn Combat Points by raiding enemy Keepers, defending against other Keepers, and by doing certain challenges. Challenges, particularly Immortal challenges, only provided a certain quantity, and can not be repeated.
Raiding Keepers was the primary way to earn Combat Points. DK Premium increased the number earned by 40 per cent.
