The Half Dragon is Warlock instead, same background with the father (Chithyss, Lord Of Ice)  who was slayed 2 - 3 years ago, and angered by the thieves that stole his inheritance etc. But he realised he needed more power so asked a Devil for Help called Maelganus and thus has the Pact of the Fiend. Nice and easy simple play style. Trying to stay directly towards fiendish spells and stuff to make him more interesting as a Character. I'm still Vain as fuck but now It makes more humour as I have an Imp as my pact of the Chain. So feel free to give the Imp a personality as to me he's basically like a Watcher who just returns continuously if he drops to 0 in combat. And he's watching to make sure I finish the deal. The deal is I get more power but have to supply Maelganus the bigger devil with 10,000 humanoid souls. So I guess I'm playing like a soul mongerer Haha, I'll be walking around with my pen and paper and my Imp witness to tempt others into signing a waiver of their life in service to Maelganus.

Around humans the Imp takes the polymorphed form of a Raven. But when I'm on my own he will probably reveal his true form. Etc

Works as my find familiar spell, as part of the pact of the Chain I can pick it to be an Imp. Also as part of the pact of the chain I can forgo my attack for him to make an attack as a reaction on my turn. So technically kind of a combatant but it isn't dumb it won't just go up to an owlbear and attack it would probably just watch as a raven above me etc.

The imps, up to you dude. If he dies it will be either another imp or the same so that's up to you. They are usually devious little things that try to temp others into evil acts. So probably pestering the party at night and squeaking at me or telepathically speaking to me telling me I should steal this or that etc.

Devil belongs to Mephistopheles' court

His father's throne is on Loft Peak the Highest Mountain in the Dragon Claw Mountain Range.
