6. Stand on one of the 4 tiles and pull the lever it will teleport you to the Archangel Marcus (min. 1 people max. 4 required)

7. The mechanics to kill the Angel is simple, you need to destroy his 4 immunities (fire, energy, poison, physical).
In order to do this you need to lure it on one of the 4 squares (red quare), set the statuettes on a given color corresponding to the given immunity such as blue and use the lever marked in white so the boss will lose resistance to energy.
Do the same with other immunities once you destroy 3 (fire, energy, poison) the boss will automatically lose resistance to physical attacks.

8. After killing the Angel you will be teleported to reward room, thats full access to The Castle.
