100 Days At Sea Companions Guide

Chapter 4 - Playstyle and Helpers. A companion and helper-unit chapter for 100 Days At Sea covering companion leads, NPC/pet/team support differences, testing behavior and team play.

Chapter intro

Quick survival answer

Quick answer

Treat companions as a support-system lead: useful enough to track, but only real once you can show how a companion is obtained, follows, fights, heals or persists.

Companion test rule

If something follows you, helps you or appears recruitable, record the prompt before naming it a companion.

Companions can be pets, NPCs, teammates, class summons or tamed units. The behavior matters more than the label.
