Homebrew Djinni Species Details

They're tiny demon like creatures that can wear different forms at will and because of this can alter speed stats according, they can be summoned on an indefinitely permenant basis by warlocks, however if the warlock dies whilst they are under their command they are free to walk the earth until they suffer too many mortal wounds and are forced to return to the demon realm an await their next summoning. They come in all sizes but for ease of use they tend to be around half a foot tall and due to being able to alter their guises come in a range of different  appearances. They cannot access their powers in this world until their master is dead and they have chosen their favourite human, under their master they can only use his spells and with their "one" they can only use as many spells as corresponds with their level, similar progress to a bard's learning of spells.
