The Emperor's Chalice is an item added by Xeno's Reliquary. It functions as an infinite water bucket when right-clicked on blocks. It can also be used to restore 1 point of hunger by right-clicking while not aiming at a block; doing so will consume 1 point of health. Shift right-clicking while placing down water will empty the Emperor's Chalice while placing down a water source block. At a very low chance, the Emperor's Chalice can activate its Emperor ability, fully recovering health and hunger or killing the player with sound and visual effects. If it kills the player, player will retain gear that was worn at the time of death, the Emperor's Chalice, and the item in their off-hand slot when revived.
