Custom/converted magic items for my homebrew campaign world “The Ninth World”. Placed here for my PCs to reference.
Mystic Cloak
Grants the attuned user +2 INT, advantage on saving throws vs magic and the ability to cask steelskin 1/day on themselves without the need for material components or to concentrate (duration doesn’t otherwise change).
Steelskin
6th-level abjuration
Casting time: 1 action
Range: Touch
Components: V, S, M (an ingot of high-quality steel that costs 50 gp; is made from bone ash and magnetite and tempered with blood; and is consumed by the spell)
Duration: Concentration, up to 1 hour
You touch a willing creature and give its skin the ability to deflect glancing blows. Until the spell ends, the target has immunity to all damage unless it takes 15 or more damage from a single attack or effect, in which case it takes that damage as normal. Any damage that fails to meet or exceed this damage threshold is considered superficial and doesn’t reduce the target’s hit points.
