The Defender Mask is a helmet armor added by Roots. The Defender Mask will automatically repair when equipped; each tick, there is a 1/80 chance of one durability being repaired, or a 25% chance of one durability being repaired per second. The Runic Tablet states it additionally "increases your [the player's] natural regeneration, even when out of food," but this appears to be untrue.
The Defender Mask is created in a Ritual. It requires a Diamond, an Iron Helmet and an Oak Wood Plank to be placed on the Casting Altar and two Oak Barks, one Wheat and one Oak Sapling to be burned in the Incense Brazier. The Ritual requires Attuned Standing Stones to be placed around it.
