100 Days At Sea Armor and Defense Guide

Chapter 6 - Defense. A defense chapter for armor, raft defense, raid prep, damage-reduction thinking and when new players should care about defense.

Field notes

How to use this chapter

Read this before the table. It is the decision the cards and rows are there to support.

Defense is the player and the raft

A weapon that wins a duel still loses the run if you die to the next hit or the raft is gone when you turn around. Treat defense as two layers. Character armor or a tankier class row is the personal layer. Raft structures and the habit of building them early are the base layer, covered in How to build a raft. Reported starter gear, including armor-like wording on some class cards, is a lead to screenshot on Classes. It is not a damage-reduction percentage. This page will not invent one.

When armor starts to matter

Early on, avoiding a fight you do not need is the defense. Armor and raft defense start to matter when trips leave the starter water, when a badge names a boss, or when a raid-style fight showed up in a video you are tempted to copy. Before that trip, check health, the weapon on Weapons, whatever recovery items you have, and a retreat line. Bosses assumes those layers exist. If they do not, the boss page is telling you to wait. Pair any new gear with a simple before-and-after note: what a hit did before you equipped it, and what a similar hit did after, if you can make that test without ending the run.

What to record

The name on the gear, whether it came from a class, a craft, a shop, a chest, or a drop, and whether it protects you, the raft, or both. Knight Armor and similar nouns stay in the mystery list until the class menu prints them. Raft pieces stay in the raft chapter until you have structure names and a sense of what enemies do to them. The mistake to avoid is collecting a stronger weapon and calling the loadout finished. Defense, healing, and a way home are the rest of the loadout, and they are the reason a hundred-day run survives a bad fight.

Chapter intro

Quick survival answer

Quick answer

Think of defense in two layers: your character needs survivability, and your raft needs safety. A strong weapon does not help if the raft collapses or you enter raids with no recovery plan.

Defense rule

Build defense before the game forces you to need it.

New players usually improve defense after a bad fight. Guidebook play means preparing before the bad fight happens.

Use this during play so you know what worked, what was risky, and what is worth repeating on the next run.

Check 1

Armor or defense source and whether it protects the player, raft, or both

Check 2

Damage taken before and after the gear if you can test safely

Check 3

Whether defense mattered during raids, bosses or long exploration
