Arc's Dutiful Armor

The armor and tools are modeled on the old forged set that the mod describes, with new sprites recreated for each piece. Materials are grouped into light, medium, heavy and unique tiers, and the heavy tier includes Heavy Iron as a separate material. A separate Excalibar material supports its own armor and tools, and the mod also adds unique ore variant blocks that yield those materials when broken.

Each armor piece carries special effects such as fire resistance, speed, strength and absorption. The body patches adjust how armor works on the player, which changes how the set feels in use. Ways to obtain these tools and armor are described in the mod's notes, and they are part of the progression the mod sets out.
