1️⃣ Unit Rarity System in ASTD X

Units come in different rarities, which determine their power and value:

• Common (C) → Starter units, weak stats.
• Rare (R) → Decent early-game options.
• Epic (E) → Mid-game units with solid power.
• Legendary (L) → Strong units worth upgrading.
• Mythic (M) → Endgame, top-tier characters.

2️⃣ S-Tier Units (Best in the Game) 🏆

These are meta-defining and essential for top players:

• Mythic Mage (AOE lightning ultimate)
• Blade King (massive DPS melee)
• Ice Queen (crowd control & slows)
• Flame Emperor (insane wave-clearer)

💡 Always save gems for these units—they carry late-game runs.

3️⃣ A-Tier Units (Very Strong) 💪

• Samurai Hero → Reliable melee DPS.
• Dragon Summoner → Great for infinite mode.
• Spirit Archer → Powerful ranged option.
• Battle Healer → Buffs and heals teammates.

4️⃣ B-Tier Units (Solid but Situational) ⚔️

• Shadow Rogue → Decent PvP utility.
• Wind Caster → Useful in specific maps.

5️⃣ C-Tier Units (Beginner/Outdated) 🐣

• Basic Swordsman
• Old Mage
• Starter Archer

These units are fine for learning but should be replaced quickly.

Some units shine not just in combat but in farming efficiency:

• Gem Farmer → Boosts gem rewards.

Perfect for speeding up progression.

7️⃣ How to Build a Strong Team 🛡️
