Resources

Resources come in different tiers like troops. There are five types of resources per tier. Once your production building levels reach level 30, you can switch to producing Tier 2 resources.

Types of Resources
Tier 1 resources are used for all Tier 1 research and troops from Tier 1 to 6 and some buildings up to level 30. Tier 2 resources are use for Tier 2 Research and troops from Tier 7 to Tier 9 and buildings from level 41 to 50 as of August 2017.
