Universal Tower Defense Z Update 4.0 Tier List

Meta Shift After 4.0

Update 4.0 elevates Moonless Sky to S+ Boundless carry status alongside Joyful Captain and The Strongest line. Flame Captain (Ember) enters S-tier for DoT raid content. Pre-4.0 units remain viable—Virtual Idol is still mandatory, and Merciless God plus Blanco Beast hold festival slots.

• Joyful Captain — universal fire DPS
• The Strongest of Today — Infinite AoE scaling
