What Is Armor 5e and Why Does It Matter in Every D&D Session
Armor categories and AC
In 5e, armor is light, medium, or heavy.
- Light adds your full Dexterity modifier to the armor’s base AC.
- Medium armor 5e adds your Dex modifier up to +2.
- Heavy armor 5e ignores Dex and sets a fixed AC.
A shield gives +2 AC, and only one shield counts. Several armors also impose Stealth disadvantage, and some heavy suits require a minimum Strength, or you lose 10 feet of speed. These lines are the backbone of every gear choice.
Getting into and out of armor
You only gain AC after the suit is fully donned. Light takes 1 minute, medium 5 minutes, heavy 10 minutes, and a shield is 1 action to don or doff. With help, doff time halves. This is why night ambushes, alarms, and travel watches need planning.
Training (proficiency) matters
Wearing armor you aren’t trained in gives disadvantage on any Strength or Dexterity ability check, saving throw, or attack roll, and you can’t cast spells while doing so. Confirm training before you swap gear mid-campaign.
Complete Guide to Core D&D 5e Armor Types
- Light armor bests: Leather armor 5e is AC 11 + Dex. Studded leather armor 5e is AC 12 + Dex and stays quiet. For Dex builds that rely on Stealth, studded leather is the steady, non-magical end state.
- Medium workhorses: Chain shirt sits at 13 + Dex (max 2) and is quiet. Breastplate is 14 + Dex (max 2) and is also quiet, making it the all-rounder. Half plate is 15 + Dex (max 2) but imposes Stealth disadvantage. Pick based on how often you need silence.
- Heavy walls: The fixed AC ladder is chain mail 16, splint 17, plate 18, with Strength tags and Stealth disadvantage on the heavy end. Add a shield when the hand is free for +2 AC.
How Spells and Feats Affect Armor Class in 5e
- Mage armor 5e sets your base AC to 13 + Dex for 8 hours on a target not wearing armor and ends if that target dons armor. Treat it as a full formula. Pick one base-AC method at a time; no stacking.
- Lightly armored 5e in the 2024 rules grants training with Light armor and Shields (and a small ability boost). Not every table has moved to the 2024 book yet, so confirm which rules set your group uses before you plan around shields.
- Mithral Armor is the legal way to make noisy armor quiet. A mithral version removes Stealth disadvantage and the Strength requirement if the base armor had either of those, while keeping the same AC. It exists for many armor types as an uncommon magic item.
Common Mistakes When Creating Epic AI Armor in 5e (And Fixes)
- Wrong formula: A classic slip is adding full Dex to medium armor 5e or assuming heavy uses Dex. Write the AC line first, then design the look. That one habit prevents most balance issues.
- Stealth mismatch: Your art screams “ghost-quiet,” but the rules piece has Stealth disadvantage. If you need silence, choose breastplate or studded leather, or use Mithral Armor to remove the penalty on a higher-tier suit.
- Overtuned homebrew: If your non-legendary set beats plate + shield with no drawback, fights will warp. Keep AC inside the standard tables, then add at most one perk and trade it for rarity, attunement, cost, noise, or a limited-use rider.
- Spell stacking confusion: Mage armor 5e is a base AC. It ends when you don armor and doesn’t mix with other base formulas. Keep it clean.
Step-by-Step Guide to Designing Armor in Summon Worlds
Why this workflow? You want rules that read fast, visuals that match the rules, and an item card your game master can say “yes” to. Summon Worlds gives you AI creation tools, image generation, collections, and character chat in one place, on mobile or web.
🔒Choose the role and lock the rules
Decide if the wearer is a scout, skirmisher, wall, or arcane guard. Pick light, medium, or heavy to match, and write the exact AC formula in the first line of your item. Add Stealth and Strength notes here as well. This prevents drift later.
🪄Generate the look
Open AI Art Generation in Summon Worlds. Pick a style preset that suits your world: Epic Fantasy, Steampunk, Anime, or Photorealistic. In your prompt, call out silhouette, material, heraldry, and wear marks. Save Extra Images for the front, back, and a close detail. Keep it in Drafts until your party reviews.
🏗Build the item card
Create an Item and add: category, AC math, Stealth/Strength notes, rarity, attunement, and one tasteful perk if the item is rare. If you want a “quiet plate,” set it as Mithral Armor so it removes the Stealth disadvantage and Strength requirement by the book.
⚡️Add class synergy
Explain who it fits best: rogue in studded leather armor 5e, ranger in breastplate, paladin in plate, caster with mage armor 5e, or a 5e armorer using Guardian or Infiltrator. This note helps your GM approve it quickly.
🌏Bind it to the world
Use Summon Worlds’ AI to write a maker, a vow, and a place tied to the suit. Two hooks are enough. Example: “Blessed on each new moon; the script warms when a promise is kept.” Publish to a Collection for easy table access.
🧪Test at the table
Open Character Chat and let an NPC react to the armor. Turn on image replies for reveal scenes. If the set has a sentient core, assign a voice and let it speak during rites.
✅Iterate after feedback
If the perk feels too strong, raise rarity or add a small cost. If it’s flat, attach a once-per-long-rest effect tied to the lore. Save Extra Images when you tweak the look so your party can see the change.
Best Armor Designs and Popular Styles for D&D in 2025
- Silent runner (light): A low-profile rig with matte studs, dark stitching, and a cowl that breaks the outline. Works for rogues and scouts who live on Stealth. Rules-true fit: studded leather armor 5e at 12 + Dex with no Stealth penalty.
- Ranger’s breastplate (medium): Hammered plates with leather joins and cloth baffles to muffle movement. Great for forest scouts and shrine wardens. Rules-true fit: 14 + Dex (max 2), no Stealth disadvantage.
- Oath-forged plate (heavy): Clean lines, vow etchings, and honest dents. Suits paladins, temple guards, and sworn knights. Rules-true fit: plate 18 with Strength 15 and Stealth disadvantage; shield adds +2.
