What should I hoard before a new Season starts in Last Z: Survival Shooter?

Before any Season transition (S2 Frozen Wasteland, S3 Biotech Lab, S4 Primal Dinosaurs, or S5 Night Falls), hoard at least 80-150 Stamina Cans for Day 1 seasonal currency farming, 350-975 Universal Gold Hero Fragments for the new seasonal S+ heroes, and 180,000+ Courage Badges for T10 research gates.

How many Universal Gold Fragments does it take to 5-star a Seasonal Hero in Last Z?

Upgrading a hero from 0 stars to 5 stars requires 975 total Universal Gold Fragments (25 for 1-star, 50 for 2-star, 150 for 3-star, 300 for 4-star, and 450 for 5-star) alongside 163,000 Skill Medals to maximize their skills.

How long does each Season last in Last Z: Survival Shooter?

Each server season in Last Z: Survival Shooter runs for 8 weeks (56 days), followed by a brief off-season settlement and server migration window.
