1 essence is bullshit 2. If you make good combinations of essence and powers, nothing can stop you.
essence of the blank
essence of the shattered limts
essence of the archmage
essence of the crafter
essence of the adventure
essence of the breeder + essence of the harem protagonist + essence of the binder + essence of the home = essence of the true harem king <made up>
essence of the mad doctor
essence of the healer
essence of the warlord
essence of the adventure
essence of the dungeon master
essence of the king
have more than five can make you a god if you push this to their limts.
