Oki how do i go on saying this... alright well in the dungeons there is like fences in the way of pathways to get further in dugeon, how must you get rid of fences to move on? helppp
You will be able to get by the fences in the second generation. The fences will still be there, but the child, being smaller, can squeeze past.
You may also have noticed some statues blocking other ways. Those are also for the second generation to solve and get past. The statues will disappear after you have completed the task they give you.
