Description

By spending countless hours in a library over several days, flipping through dusty old tomes, trying to make sense of the information given him as a "gift" for completing his last job, Kurt was able to find a way to imbue specific types of rings with demonic powers.
Using either a blue or black gemstone placed in a ring as a conduit Kurt is now able to draw upon the powers of the underworld and summon forth blue hellfire to fell anyone opposing him.
This came at a price however, as he had to perform a sacrificial ritual, making two deep vertical incisions into each one of his palms, in order to make the power usable.
As Kurt prepares to fire, the gemstone on his ring begins to shine a bright blue, evident to any onlooker.
Following this a hellish maw will open on the palm Kurt's wearing his ring on, revealing a bottomless black pit with countless rows teeth, before a ball of blue flame comes spiraling out of its depths, accompanied by something that sounds like a mix between a laugh and a scream.

Whenever not in possession of a fitting ring, the maws will refuse to open, and be completely useless to Kurt.
Whenever the power is not in use, Kurt wears leather gloves to conceal his palms.
