[RPG] the speed penalty for Chainmail


Does it do like -1 to speed? What is the speed penalty for using Chainmail?

Best Answer

Heavy Armor. Heavier armor interferes with the wearer’s ability to move quickly, stealthily, and freely. If the Armor table shows “Str 13” or “Str 15” in the Strength column for an armor type, the armor reduces the wearer’s speed by 10 feet unless the wearer has a Strength score equal to or higher than the listed score. - PHB, p144

Chain Mail is Heavy Armor, with a Strength Requirement of 13. If the character is at least STR13, they take no speed modifier for the weight of the armor.


If you wear armor that you lack proficiency with, you have disadvantage on any ability check, saving throw, or attack roll that involves Strength or Dexterity, and you can’t cast spells. - ibid

Some armors, including all heavy armors, impose a disadvantage on Stealth checks, regardless of proficiency. There's no way around it for heavy armor. For medium armor, the Medium Armor Master feat allows you to ignore the stealth penalty, among other benefits.

Heavy armor doesn’t let you add your Dexterity modifier to your Armor Class, but it also doesn’t penalize you if your Dexterity modifier is negative. - PHB, p145.

And lastly... Dwarves don't care. They only have a speed of 25, but it's unaffected by heavy armor (PHB, p20). It doesn't get them out of the penalties for lack of proficiency, though.
