 * Random traps (pressure plates) in empty rooms (north side, far corners) on top floor, en route to Rubyeyes
 * Avoid the beacon ray once it is lit - it will cause bodily damage or even kill the character.

Walkthrough

 * Use the 3 levers marked on the map to open the barricade to the stairs to the 2nd floor. Splitting up will make this go much faster as they are far apart. Two of them are in the Mausoleum beneath the stairs, the other is on the ground floor. (Red: Up the middle entry stairs, all the way north, one room west. Yellow: Down the left entry stairs, head northeast. Blue: Down the right entry stairs, go east via south, in the large cathedral room due east, the switch is upstairs.)
 * Talk to Vladimir on the 2nd floor, no matter what you say he will attack you. He will drop a key once killed. You do not need to do anything else on the second floor.
 * Head to the Mausoleum and place the skull there.
 * After placing the skull, arrange the mirrors to hit the relay, then use the stairs nearby to go up and access the beacon area.
 * Kill the boss and solve the tile puzzle while avoiding the trapped tiles to activate the beacon.
