Fuse Elements
There are 5 basic resources. Fire, water, earth, metal and wood. These resources can be fused into elemental crystals. Crystals are then used to build towers or crushed into crystal shards.
Build towers
Start by building basic towers from core 5 elements. Each tower is unique and counters golems made of opposite elements. After you build a tower you can choose to upgrade a tower by combining its base elements with another element.
Send Golems
In order to win you need to send waves of golems to march on the enemy crystal core. Golems have 3 parts. Body, body-armor and shield. Each golem part can be made of any element. Choose the design for your golems and send them. Sending a golem also rewards you with elemental resources income.
Upgrade Hero
You can directly control your hero. Hero weapons can be upgraded with elemental affixes. Upgraded hero weapon can significantly counter golems made of opposite element. It is completely optional to use hero.
