Ensnared Demon

An Ensnared Demon is a Relic acquired in Castlevania: Lords of Shadow 2.

Description
"When in the 15th century a group of strange scholars presented the prototype for the first steam engine, it seemed impossible to explain how they could have invented such a sophisticated machine with the existing tools and knowledge. It would have been impossible, except that its framework did not hide human technology but rather a complex mechanism fed by the magical energy of a demon trapped in its core."

Gameplay
The Relic, like most, is quite handy to have in a tight situation. When used it will provide unlimited Chaos and Void magic allowing you to either deal out huge damage or quickly build health.
