Armor of Resistance

Armor of Resistance is armor that grants the wearer resistance to one type of damage. There is also one known example of a Shield of Resistance that may or may not function as the armor does.

Description
Armor of Resistance can be light, medium, or heavy. An attuned wearer of the armor is granted resistance to one type of magical damage (ie, not slashing, piercing, nor bludgeoning).

Campaign 1
A duergar general, who has commanded over a camp beneath Kraghammer, wore blackened plate armor of fire resistance, which was packed into Grog's Bag of Holding once the general was defeated by Vox Machina and unused since then.

Vax'ildan had a studded leather Armor of Acid Resistance since pre-stream, and until his last mention of wearing it in. During the Chroma Conclave attack, Vax/Liam said that the armor had been transferred to someone else, and it appeared six episodes later in Vex's hands. She traded the armor to Scanlan in exchange for Coldsnap Leather Armor, since Scanlan was preparing to teleport into the acidic belly of Umbrasyl. Much later, Scanlan's simulacrum wore some unused Armor of Acid Resistance.

Vox Machina looted a Plate of Radiant Resistance from the corpse of a Remnant cultist, killed by the group on the ziggurat inside the Smouldercrown Mountains.
