Immunity Band

The Immunity Band is a ring that can be found as a special item in the Mines on floors 100 and below, the Quarry Mine, and the Skull Cavern. When equipped, it increases Immunity by 4, making it one of the few pieces of equipment that directly raises this defensive stat. Wearing a second Immunity Band adds another 4 Immunity, so two bands together provide a total bonus of 8.

Like other rings, it occupies one accessory slot and stacks with other equipment that affects Immunity, including several boots. This makes it most useful when building toward high total defense or when trying to reduce the chance of negative status effects that are mitigated by Immunity. The bonus is especially noticeable in dangerous areas where survival depends on durability rather than raw damage output.

• It is a ring, so it can be combined with another ring for a second copy of the effect.
• A second equipped Immunity Band grants an additional 4 Immunity.
• Other equipment that affects Immunity includes Leather Boots, Rubber Boots, Tundra Boots, Thermal Boots, Firewalker Boots, Space Boots, Cowboy Boots, Dark Boots, Genie Shoes, Leprechaun Shoes, Emily's Magic Boots, Cinderclown Shoes, Mermaid Boots, and Crystal Shoes.
• It can be used in dyeing as a purple dye at the dye pots in Emily's and Haley's house on 2 Willow Lane.

Because it is a special-item ring rather than a crafted or purchased accessory, the Immunity Band is generally obtained through exploration and luck while delving into the deeper mines. Players who favor defensive setups can pair it with other immunity-boosting gear to maximize protection, while players who do not need the stat may still keep one for dyeing purposes or for later use in a specialized equipment loadout.
