Armor
The Armor table lists the game’s main armor. The 
table includes the cost and weight of armor, as well 
as the following details:
Category. Every type of armor falls into a category: 
Light, Medium, or Heavy. The category determines 
how long it takes to don or doff the armor (as 
shown in the table).
Armor Class (AC). The table’s Armor Class column 
tells you what your base AC is when you wear a 
type of armor. For example, if you wear Leather 
Armor, your base AC is 11 plus your Dexterity 
modifier, whereas your AC is 16 in Chain Mail.
Strength.  If the table shows a Strength score in the 
Strength column for an armor type, that armor 
reduces the wearer’s speed by 10 feet unless the 
wearer has a Strength score equal to or higher 
than the listed score.
Stealth.  If the table shows “Disadvantage” in the 
Stealth column for an armor type, the wearer has 
Disadvantage on Dexterity (Stealth) checks.
Armor Training
Anyone can don armor or hold a Shield, but only 
those with training can use them effectively, as 
explained below. A character’s class and other fea-
tures determine the character’s armor training. 
A monster has training with any armor in its stat 
block.
Light, Medium, or Heavy Armor
If you wear Light, Medium, or Heavy armor and lack 
training with it, you have Disadvantage on any D20 
Test that involves Strength or Dexterity, and you 
can’t cast spells.
Shield
You gain the Armor Class benefit of a Shield only if 
you have training with it.
One at a Time
A creature can wear only one suit of armor at a time 
and wield only one Shield at a time.
