Universal Tower Defense Z Hero Relic Set — Farm & Best Units
Universal Tower Defense Z Hero Relic Set guide for July 2026. Crime Fighting Extraction World Events and debuff synergy.
Set Overview
The Hero Relic Set is a three-piece debuff-focused gear set from Crime Fighting Extraction World Events in Update 4.0. Each piece amplifies status effects—ideal for units applying Slow, Stun, or other debuffs like Neko Captain (Lightning) and support carries.
Pieces only enter your inventory after a successful Final Extraction. Mid-run World Event drops sit in a temporary pool until you extract.
How to Farm
Enter Crime Fighting Extraction and approach World Events with red exclamation markers. Read each event's reward table—only commit to events listing Hero Set pieces. Solo runs take 25–35 minutes; coordinate Final Extraction timing so you do not lose pooled drops.
Multiple World Events spawn per run, giving several roll chances before the Final Extraction deadline.
Best Units to Equip
Neko Captain (Lightning) is the standout carrier—Hand on Paw and Follow-Up passives stack with Hero Set debuff amplification. Support units that buff allies while applying Slow also benefit. Pair with Heaven Piercer on formation-heavy teams for overlapping buff potency.
