Hello Everyone I have a question and maybe you could help me; Whenever i try to summon a familiar nothing happens (I had a familiar at the end of BG1 - a Faerie Dragon). Casting the spell and choosing one of the other 2 familiars sort of works; but when you talk with them they disappear - With the Faerie Dragon nothing happens (as in the video) Any idea on why this happens or how I could fix it?
