Deep sleep is a status effect that makes players unable to move or perform any actions. This effect is cast by the Pan Pipes if played by a Satyr Elder. Sometimes these hostile merrymakers can be seen playing the pan pipes from afar, giving players fair warning that they are at risk of heavy sleep if they choose to proceed. Without intervention, sleeping players can suffer major loss of health and likely death from unrestrained enemy attacks.
Players experiencing this extreme form of sleep cannot be awakened by being pushed or attacked as they can be while experiencing light sleep. However, another player can use a Scroll of Awareness to revive other nearby players who have fallen into deep sleep.
There are ways to resist falling deeply asleep before the effect is cast. Potions of Rage can be used to agitate the player, giving them complete resistance to sleep. Additionally, an Amulet of Sleep Resistance can be worn, which will provide an additional 20% chance of deep sleep resistance, though higher players may opt for a Shield of the Mind, which offers 14%.
