This time we got wiped badly compared to level 3 land... 3-gates to the castle are guarded by 3 bosses... inside the castle is one big boss guarded by 6 sub-bosses that are immune to all elements/physical except one type. We were able to kill the boss guarding middle castle gate only, the other ones one-hit kill us all.... Here are a few pictures...
