About this game
Enemies spawn every round and march toward your Crystal Tower.
Defend it against waves of increasingly stronger foes.
Each round, you’ll receive a gear draw ticket.
Use it to obtain random gear materials, and upgrade your equipment to higher tiers.
Between enemy waves, there are moments of peace.
Take that time to enter the mine and collect valuable resources.
Mining provides various materials that help your character grow.
Every 10 rounds, a powerful boss will appear.
These bosses are extremely tough.
If you're struggling to defeat one, check if you're lacking boss-specific equipment or abilities.
From the Unique tier and up, each piece of gear has its own skill.
Use these unique skills strategically to build the ultimate gear combinations.
