S1 Black Tide Hunt OrderS1 Black Tide Hunt Order

The S1 season warm-up drop: elites and bosses on the stages drop Kuroshio Hunting Coins and Season Surprise Treasures. Coins buy the event exchange — robot, collectible and gear chests down to plain consumables; the surprise chests pay Gene Awakening Cards, tonics, shards and diamonds. Quests stack chests and gene cards, the battle pass levels on stamina spent, and the packs hand out coins for free, for an ad view and for diamonds. Coins left over when the event ends turn into gold.

Coins and treasures drop from elites and bosses on campaign stages — both when you play and when you sweep. A stage rolls 3 elite and 2 boss drops: about 10 coins and 2 treasures for 10 stamina. The daily coin cap lands after roughly 15 stages; sweeping also costs a sweep voucher.

Coins left when the event ends turn into gold at 1.5 per coin.
