Understanding Unit Rarity and Summon Rates

Before diving into specific units, it’s crucial to understand how the game’s gacha system works. Universal Tower Defense uses a rarity-based summoning system that determines how likely you are to pull each unit.

Official Summon Rates (Verified from Wiki):

• Secret Units: 0.00625% (Extremely rare, game-changing power)
• Mythic Units: 0.5% (Very rare, top-tier performance)
• Legendary Units: 2.0% (Rare, strong mid-to-late game units)
• Epic Units: 16.0% (Uncommon, good early-to-mid game units)
• Rare Units: 81.5% (Common, starter units)

Pro Tip: Save your gems for banners featuring Mythic or Secret units, as these will have the most significant impact on your long-term progression. While Rare units can carry you through early game, you’ll want to replace them with higher rarity units as soon as possible.

Common Mistakes to Avoid

Based on analysis of top players and common beginner errors, here are the most crucial mistakes to avoid:

1. Spending Gems on Every Banner

Mistake: Summoning on every banner without planning Solution: Save gems for banners featuring S-Tier units or units you specifically need for your team composition

2. Ignoring Economy Management

Mistake: Focusing only on DPS units without economy Solution: Always include at least one economy unit (Fastcart or Namo) in early game, then replace once economy is established

3. Not Investing in Traits

Mistake: Leaving units with default traits Solution: Always reroll traits for S-Tier or A-Tier traits, especially on key units

4. Overlooking Unit Synergies

Mistake: Building teams without considering unit interactions Solution: Plan team compositions around synergies (e.g., burn teams, Team 7 compositions, Pirate Crew bonuses)

5. Neglecting Ethereal Upgrades

Mistake: Not investing in Ethereal levels for key units Solution: Prioritize Ethereal upgrades for your most important units, especially Mythic and evolved Legendary units
