thank you. the two bosses you didnt reach are the ones that break the pattern most, one shuts and you cant touch him till he opens, the other puts units on the floor you have to clear first. the first four lean on the circles a lot more so from where you stopped thats a fair read. and that trail is on purpose, you can grab the chest and head back down normally, but going too far to the right up there lets the tide take the road behind you, the trees are walkable up there tho you can walk thru them and cut straight to the dungeon entrance.
