Fiendish Tethers

Wondrous item, uncommon (requires attunement by a tiefling)

These spiked manacles fit around your horns. While wearing them, they radiate with harmless embers. You can use an action to cast the find familiar spell from the manacles, instead of its normal casting time. When you do, the familiar takes the form of an imp. The familiar remains for up to 1 hour.

Once this property of the manacles has been used, it can't be used again until the next dawn. If you can cast a spell of 1st level or higher without expending a spell slot using your Fiendish or Infernal Legacy trait, you can forgo casting one of them to regain a use of this property early (no action required).

While my hands remain unbound, I am forever tethered to my progenitors. My neighbors rebuke me, but to those below I am a person of station. I choose to wear the chains of my inheritance—I choose to bind myself to the flames of hell.
