Evil Castle 66 to 70F

Ignore mobs, and attack only the boss. Once the boss dies, everyone else dies too. However there are 2 issues. Blue mouth hand monster's random target can screw you, and boss's HP is so high.

In order to avoid blue mouth's attack, use taunt tank 1st and position Exile adjacent to the tank. Red mouth will attack the taunt tank and put charm on Exile. Then let charmed Exile to attack and put concentrated fire on the tank. By doing this, blue mouth will attack the tank, not random target.

To kill the boss, strong inc. boost DMG and weakening are needed. For this Scarlet and Orienne are excellent. Then finish it up with Maxwell coffee. Yummy! I used Rage+Rage/Fatal runes on him. Sometimes he failed to kill, so might have to try again. BTW I didn't put any runes on Exile.

Could not take down the boss by Maxwell despite adding Denarisa, so I used Lyudmila instead.
