Elven Chain Mail
Ornate Mail of an Elvish Origin
Counts as light armor. If you roll a 1 on the degradation die roll an additional D8. The armor only degrades if the second roll is a 1 as well.
Looted from the horde of Gore Eater in the Grave of Words. This mail was given to Sans by Fats. It is very ornate and gaudy, but somehow weighs next to nothing. Other than that it seems to function exactly like chain mail.
