In Legends of Tomorrow season 5 episode 5 titled 'The Mortal Khanbat', Constantine calls a mysterious creature to heal him from lung cancer. What is this creature (character) and what are the powers that it possesses?
He’s trying every mystical solution he can find - bringing back a pooka from last season, making Nora’s kid come to the House of Mystery to wish him healthy again, shouting at archangels to cut a deal, something untoward with Ray’s foreskin. As each attempt fails, he lashes out harder and looks and acts more pathetically desperate. It’s so good, and so true to how I see the character in my head.
Quoting from the wiki entry:
Healing: they are able to heal injuries as one was shown to heal a wound on Constantine's forehead.
