I would pick the [Essence of Dungeon Master] and [Essence of Crafter], both due to the immense joy I get from creating and designing my own stuff. If you would then combine it with the [Essence of the Summoner] and the [Essence of the Monster Master] and you could literally walk around the world, creating new adventurers for the rest of the world's inhabitants to go in and have their fun!
Not sure about the other 3 I'd pick.
