Arcane Conduit Harness Wondrous item, uncommon (requires attunement by a sorcerer, warlock, or wizard)
This device allows daring spellcasters to channel raw magical energies, offering a measure of control over experimental spellcasting despite its inherent risks. It consists of leather straps, flexible tubing, glass cylinders, and plates, bracers, and fittings forged from arcanium—a magic-infused alloy—all assembled into a wearable harness. The item weighs 8 pounds.
While wearing the arcane conduit harness, you can use it as an arcane focus. In addition, while attuned to it, you can attempt to cast a spell that you do not know or have prepared. The spell you choose must be on your class’s spell list and of a level for which you have a spell slot, and you must provide the spell’s components.
You expend a spell slot to cast the spell as normal, but before resolving it you must make an Intelligence (Arcana) check. The DC is 10 + twice the level of the spell slot you expend to cast the spell.
On a successful check, you cast the spell as normal, using your spell save DC and spellcasting ability modifier. On a failed check, you cast a different spell from the one you intended. Randomly determine the spell you cast by rolling on the table for the level of the spell slot you expended. If the slot is 6th level or higher, roll on the table for 5th-level spells.
If you try to cast a cantrip you don’t know, the DC for the Intelligence (Arcana) check is 10, and on a failed check, there is no effect.
