Mid-game: Grinder for material recycling → Flintlock Pistol for Desert Island boss → Medkit stock for island runs.

Pre-Volcano: Iron Sword and Iron Armor from Shipwreck Island Iron. Lava Guardian punishes undergeared groups — see bosses.

Late game: Upgrade to Scoped Rifle tier weapons before Kraken Zone. Bulk repair kits and warm food before Ice Island.

Complete recipe trees on crafting. Material farms tied to islands. Camper class (+10% building speed) accelerates raft upgrades per raft building.

Common Mistakes to Avoid

Skipping code redemption on Day 1 — expired codes like BERMUDA on expired prove time-limited rewards vanish permanently.

Sailing to Desert Island without a ranged weapon — Sand Worm arena punishes melee-only loadouts from bosses.

Spending Pearls on luxury classes before Day 10 — wastes 100DAYS value; read all classes first.

Entering Volcano Island without Iron Armor — Lava Guardian fire damage wipes unprepared groups.

Ignoring co-op role balance — four DPS without Medic/Crewmate fails Kraken on boss fights.

Trusting random Trello links — no official board; use trello wiki reference instead of scam login pages.

Hoarding Pearls indefinitely — class and companion timing matters mid-game; see survive day 100 spend gates.
