Whispers of the Ancestor

In a ritualistic process lost to most, a caster of the Hulbren clan can reach across realms to call upon the spirit of an ancestral guide. Upon completion, an ethereal visage forms, pulsing with mystical energy and tethered by the emotional resonance of the caster's own memories. The caster holds a conversation with the spirit, gaining insights and guidance but must succeed on a DC 15 Charisma saving throw per query. On a failure, the response is cryptic, and the caster suffers 1d4 psychic damage from the overwhelming spiritual burden. The spirit shimmers randomly from form to form, reflecting past variations of it's existence, while whispers of old wisdom echo faintly around the caster, heard only by them.
