The fiend warlock gains a powerful ability at 1st level, and the great old one warlock gets 2 unique spells (1 situational and 1 good one). Dark One's blessing is broken in this game if you can consistently get kills with your warlock (which you should be able to do lol). I'd like to see it bumped down to once per short rest. The GOO should get telepathy (which i know is hard in a video game), but perhaps giving them a low power telekinesis (limit 20 pounds, range 60 ft) to throw stuff with?
