Adamantite: +1 DR, 0.75 times weight, +499 CF. Cannot be combined with Baatorian Green Steel, Meteoric, Mithril, or Orichalcum. Gives the armor a level of the Hardened Enhancement (see p. B47).

Baatorian Green Steel: 0.6 times weight, minimum of +3 CF, probably more. Extremely rare, as it comes from Baator, on the Outer Planes. Cannot be combined with Adamantite, Elven, Meteoric, Mithiril, or Orichalcum.

Drow: Drow made armor is naturally enchanted by years of exposure to Underdark radiation. Unfortunately, it weakens when exposed to sunlight, reducing DR by 1 per day thereafter until the item is useless. Gives a bonus to DR up to +5, but may not be further enchanted to improve this. +10 CF x (bonus squared).

Dwarven Mithril Mail: 0.75 times weight and +1 DR for +449 CF or +2 DR for +599 CF. Any mail armor. Cannot be combined with Adamantite, Elven, Meteoric or Orichalcum.

Mithril: 0.5 times weight, +299 CF. Cannot be combined with Adamantite, Baatorian Green Steel, Meteoric or Orichalcum.
