First 30 minutes
Redeem every active code immediately. CRAFTNERF! and JJKUPDATE have no progression lock, so claim them right after joining. Place Luffy on the longest lane and let him farm early waves.
Wave 1-25 survival
There are no checkpoints between Wave 1 and Wave 25. Spend your opening cash on a wide AOE early unit and avoid spending rare Trait Shards on filler. Save resources for your first real carry.
Wave 25 checkpoint
Reaching Wave 25 unlocks the First Checkpoint badge. Your run no longer restarts from Wave 1. Redeem SRYFORSHUTDOWN! at Wave 26 to claim a free Kenpachi.
First 10 minutes of trait rolls
Do not chase Corrupted on starter units. Roll for Celestial or Void Emperor at most until you own a God-rarity unit. Save Trait Shards for the high-stakes rolls.
When to expand the base
Wait until you have a stable God-rarity carry or you cannot deploy more units. Expanding early is a common waste pattern.
