100 Days At Sea Companions Guide

Companions are collectible allies in 100 Days At Sea that passively buff stats, gather resources, or boost combat while you explore islands and fight bosses. Earn them from Companion Chests — including the free chest from STRANDEDDEVS on codes — Pearl-purchased chest tiers, and island rewards. Each player equips one active companion. Zookeeper class (+25% companion buff effectiveness) multiplies every perk listed below. This guide covers all sixteen companions, chest costs, drop rates, and pairings with classes on all classes and loadouts on builds.

Companion Strategy and Chest Priority

Day 1: Open STRANDEDDEVS free chest immediately after how to redeem. Any Fisherman's tier roll beats no companion — equip best combat or sustain perk for your class.

Mid-game: Save Pearls for Warrior Chest when melee DPS needed (Swordfish chase) or Pirate Chest for gun builds (Parrot, Pirate Gunner). Magma Chest after Volcano Island unlock for Lava Snail.

Zookeeper players: every companion perk listed above gains +25% effectiveness — Frog hunger reduction becomes substantial; Swordfish melee bonus rivals extra weapon tier.

One companion slot only — do not hoard chests without opening. Inventory space and equip timing matter before Ghost Captain on Shipwreck Island per boss fights.
