Step #3: Missy

To get boss out you need to kill all Old Servant Ladies first once boss appear hero WS can lure boss to bottom right corner and fight her there ! WS hero fight boss using the same skill describe in previous steps. Other hero could partially fight boss but make sure you all protect WS & ES hero is boss body guard(s) come out that very important.
Step #4: Manor Owner

All hero go up except ES need to activate step and fight lamps. If you team has WB hero, this hero can get into the middle of the stage and lure boss to the position showed in the picture. Once boss lock make sure boss walk "patrol" otherwise he will use nasty skill and it hard to complete this stage. The most important part in this stage is to absorb poison throw by boss, which allow BC hero to copy the poison and pass it on to boss in later steps.
Until next time ... Enjoy ! your game ;)
