Several buildings can be built in your Stronghold which produce special resources for Conquest. The resources are as follows:
Stones - used to build and upgrade Watchtowers in Conquest.
Wisdom - used to unlock upgrades in the Tech-Tree.
Troops - used for attack and defence in Conquest. Troops can be assigned to Heroes or Watchtowers to boost your attack or defensive capabilities and gain an advantage over your enemies.
Builders - used to build and upgrade Watchtowers on the Conquest map.
