In reallife, a chain armor *always* has padding under it, typically a gambeson (tunic quilted with various padding, such as leather rags and horse hair), but alternatively layers of heavy wool tunics.
At least in my campaigns, ‘chain shirt’ armor includes the ‘padded’ armor by default, just like it includes a ‘helmet’ by default. If for some reason it was lacking, then the chain armor would be defective and the AC would lower, missing the +1 from the padded armor.
But the mithril shirt is something different. It can be worn explicitly without padding. Yet it dampens bludgeoning.
I see many of you have come to answer this question.
Does anyone have a list they can compile from the materials I listed? And of course, optional, other fantasy materials.
Any material that is equal to another, they can be listed as such, "material 1 - material 2"
Right, so chainmail has the padded gambeson as per the PHB description(and the stealth disadvantage associated with padded armor), and chain shirt does not. In fact a chain shirt doesn't look like a chain shirt because it as a layer of cloth or leather on the inside and the outside.
If it were up to me chainmail with or without padding would do little to reduce bludgeoning damage. At your table you can have whatever rules you want. But I don't think there is sufficient evidence in RAW or historically (in D&D or LOtR) to imagine that mithril metal has some unexplained bludgeoning resistance other than the *un*explainable resistance already granted to chainmail.
I believe that Tolkien was describing a chain shirt made as a single piece, with the under padding stitched onto the chain to make a single garment. Fine chain will easily conform to the shape of the under-layers.@snickersnax, @kap'n Kobold
But there is no ‘padding’ under a mithril shirt. It is silk-like. And often it is worn as an undershirt.
Somehow this silky metal mesh is able to dampen bludgeoning weapons.
Well-fitted chain is pretty elastic, but only to a certain point, and provides a reasonable amount of resistance to bludgeoning damage. Combined with the padded leather underlayer it spreads out impact. Obviously it is more effective against slashing weapons, but quite frankly 5e isn't granular enough to deal with weapon types vs armour types etc.Right, so chainmail has the padded gambeson as per the PHB description(and the stealth disadvantage associated with padded armor), and chain shirt does not.
