Manage 4 resources: Gold (kills), Stone (quarries), Crystal (rare, boss drops), Mana (regenerating).
Resource Deposits: Stone nodes and Crystal nodes appear on buildable tiles. Build quarries on stone, mine crystals for one-time rewards.
Build Quarries (40g/20s) on stone nodes. Build Mana Wells (30g/15s) anywhere to increase mana regen.
Market: Trade resources. Economy is key - invest in quarries early for long-term gains!
Towers: Basic (gold), Stone (gold+stone, high armor), Crystal (gold+crystal, massive damage), Mana Spire (mana drain, no gold cost).
Research: Upgrade quarry rate, mana regen, tower discounts, and crystal drop chance.
Siege enemies destroy quarries and wells! Protect your economy infrastructure.
