Guide to Find Out Mana Towers Usage
All towers state their mana usage in their upgrade menu.
For most towers, it’s Mana per shot. You’ll have to figure out how much that is, with their RPM rate of fire.
For Frost Keeps, it’s mana per second. Frost Keeps do the same thing, costing the same mana, 24/7.
Please note: Frost Keeps specifically are bugged in their display. All towers use more mana as they go up in level, but Frost Keeps always say 2/s mana cost. They do seem to use more mana though as they go up in level.
