What Plate Armor does
- AC 21 does not improve with Dexterity. Compare armor options using your actual Dexterity modifier rather than their base AC alone.
- It imposes Disadvantage on Stealth checks; consider that cost if the group relies on sneaking.
- Strength 15 avoids this armor’s listed Speed penalty. The calculator flags the penalty when your Strength is lower.
You have a bonus to Armor Class while wearing this armor. The bonus is determined by its rarity. This is the legendary Plate Armor (+3) variant. Its magic bonus to AC is +3, in addition to the base armor's normal Armor Class.
