I wrote about Aborek as "I wants a ladder added to this floor to go to a different boss room", but how about just changing Aborek's creature more easily?
Aborek is an middle grade dungeon, but We do not have much opportunity to go.
More opportunities to go if you can adjust as much as you can clear at 10 people party.
It might be interesting to have boss (Dragon Golem Lich) in the lower layer and Wraith Skelton Archer Phase Serpent.
(Skelton Archer please lower attack power)
Disadvantage ... The number of places that can be played with a small number of people will decrease.
It makes shopping at silver leaf stores difficult.
