The Warden Core - A Pulsing Light Source

If an incredibly brave player was to kill the Warden, they would obtain the Warden Core, which is what I would describe as the three glowing heads inside the chest of the Warden. This item is a light source, and it is very special because it pulses like it did when it was inside the Warden, making the same beating sound, and emitting light in short bursts, causing a fluctuation in the light level around it. Some may see this as potential for lag, but since this item is dropped by the warden, it would take an incredible amount of effort to cause such lag to occur. Also, all warden cores in the world would beat in sync, you can’t desynchronize them to potentially experience any more lag.
