The Masked Dwarf

[sightlessrealit]

So the idea is simple & very impractical from a mechanic stand point.

So a Mountain Dwarf that multi classes an Immortal Mystic & a Hexblade Warlock.

The Character Concept is based around the "face hidden by a veil(in this case mask)" quirk and the "Listening to an imaginary friend(sentient weapon)" quirk from the Mystic Class. So first level would have to be Mystic.

Starting level 5.

So while impractical how best should I go about doing this. I don't want an even split but I would at least like 5 levels in either of the classes.
