What armor 5e means for character defense
In D&D 5e, armor defines how hard it is to hurt you. Armor 5e covers light, medium, and heavy categories, each tied to class proficiencies and AC calculation. Armor grants a bonus to your Armor Class, reducing damage by increasing the difficulty of hits. Understanding armor 5e helps you balance defense, mobility, and resources. This guide explains every armor type, AC basics, and how to select armor that fits your class, role, and campaign constraints.
Armor categories and how AC works in 5e
Armor in D&D 5e is divided into three main categories—light, medium, and heavy—each with specific rules for Armor Class, speed penalties, and proficiency. AC is a derived statistic calculated from armor, shield, Dexterity modifier, and other modifiers. You generally add your armor’s bonus to your Dexterity modifier (subject to restrictions) to determine AC. Understanding these categories and rules ensures you make informed choices about defense, speed, and survivability.
Light armor in 5e
- Padded: AC 11 + Dexterity mod; cost 5 gp; weight 1 lb
- Leather: AC 11 + Dexterity mod; cost 10 gp; weight 2 lb
- Studded leather: AC 12 + Dexterity mod; cost 45 gp; weight 3 lb
- Hide: AC 12 + (Dexterity mod if +1 or lower); cost 10 gp; weight 2 lb
Light armor suits classes that rely on Dexterity, such as rogues and some monks, because it rarely restricts Dexterity benefits and imposes no speed penalty.
Medium armor in 5e
- Chain shirt: AC 13 + Dexterity mod (max +2); cost 50 gp; weight 20 lb
- Scale mail: AC 14 + Dexterity mod (max +2); cost 50 gp; weight 20 lb
- Breastplate: AC 14 + Dexterity mod (max +2); cost 400 gp; weight 20 lb
- Half plate: AC 15 + Dexterity mod (max +2); cost 750 gp; weight 20 lb
Medium armor balances defense and flexibility. Many fighters and clerics use medium armor, accepting a Dexterity cap to gain better base AC and access to useful traits like stealth movement options.
Heavy armor in 5e
- Ring mail: AC 14; cost 30 gp; weight 40 lb
- Chain mail: AC 16; cost 75 gp; weight 50 lb
- Splint: AC 17; cost 200 gp; weight 50 lb
- Plate: AC 18; cost 1500 gp; weight 60 lb
Heavy armor delivers the highest AC but slows you substantially. Most classes that can wear heavy armor are frontline tanks, benefiting from high AC at the cost of speed.
Proficiency, speed, and armor mechanics
Using armor you’re not proficient with imposes disadvantage on Dexterity-based skills and prevents you from adding your Dexterity modifier to AC. Speed penalties apply unless your class ignores them. Medium and heavy armor also impose fatigue, reducing movement by 10 feet unless you’re proficient. Choose armor that matches your class proficiencies and mobility needs.
Shield benefits and limitations
A shield adds +2 to AC while you wield it in one hand. Two-weapon fighting and some class features limit shield use, so weigh defense gains against action economy. Shields are a simple, effective way to boost AC for lightly armored characters or off-hand options for some builds.
Stealth and broken states
Armor can affect Stealth checks. Light armor is usually better for stealth, while heavy armor imposes penalties. Broken armor provides no AC bonus and requires mending or magical repair. Tracking armor condition can matter in gritty campaigns, though it’s often abstracted for simplicity.

How to choose armor by class and role
Fighters and paladins often wear medium or heavy armor, balancing AC, endurance, and features like Action Surge. Clerics and druids typically use medium armor and shields, while barbarians favor lighter gear to maximize Rage benefits. Monks usually avoid armor to preserve Unarmored Defense, and rogues prefer light armor to protect Dexterity skills. Selecting armor should align with survivability needs, skill utility, and campaign pacing.
Buying, maintaining, and upgrading armor
You can buy standard armor from most vendors; rare or masterwork pieces may require special sources. Mending repairs nonmagical armor at a cost and time. Magical armor provides enhanced AC or resistance and is attuned to you. Consider availability in your campaign and downtime options when planning gear upgrades.
Summary: optimizing defense with armor 5e
Armor 5e is central to survivability and tactical play. AC, speed, proficiency, and cost vary widely across light, medium, and heavy options. Choose based on class proficiencies, role in the party, and campaign constraints. Pair armor with a shield when viable, track condition if your DM uses it, and leverage magical enhancements to amplify defense without sacrificing mobility.
