Heart of Sorrow

The Heart of Sorrow is large red crystal with a 20 ft. radius, located in area K20 of Castle Ravenloft. It serves as a damage absorber for Strahd von Zarovich, in that up to 50 hit points of damage he sustains can be deflected to the Heart before it breaks. The Heart regenerates all damage to it every dawn so long as it possesses 1 hit point or more. The Heart is protected by animated objects and Strahd will send vampire spawn to attack anyone who damages it.

If intruders try climbing the spiral staircase of the tower leading to it, the Heart can shake the staircase and potentially cause the intruders to fall all the way down the tower.
