Universal Tower Defense Currency

Gems, coins, and resource management strategies

Gems
Primary summoning currency

Gems are the main currency used to summon new units. They are essential for building your roster of powerful characters.

How to Earn Gems:

  • Complete Story Mode missions
  • Finish daily and weekly quests
  • Participate in limited-time events
  • Redeem active codes (check Codes page)
  • AFK farming in specific modes (see AFK Farming Guide)
  • Achievement rewards and Level Milestones (up to 7,000 gems total)
  • Battlepass progression rewards

AFK Gem Farming Method:

For maximum gem yield, farm Story Mode: "Ninja Forest - Act 1: Greedy Treasurer" on Easy difficulty. Use the Difficulty Meter to multiply rewards:

  • 300% difficulty = 144 gems
  • 1000% difficulty = 228 gems
  • Use macro tools (Informal Task) for AFK farming
  • Set modulation to 75% for balance of challenge and reward

Best Use of Gems:

Save gems for banner summons featuring S-tier and Mythic units (Kenpachi, Kuriato, Ace, Sasuke). Avoid spending on commons. Consider summoning during rate-up events for better chances at powerful units. Prioritize top-tier banner units before rerolling traits.

In-Battle Currency
Money generation during stages

During battle, you generate money over time and from defeating enemies. This currency is used to deploy and upgrade your units during the stage.

Money Management Tips:

  • Deploy Farm units early for economy advantage
  • Balance between deploying new units and upgrading existing ones
  • Killing enemies faster = more money generation
  • Don't overspend early - save for expensive carry units
  • Learn optimal unit deployment order for each stage
