The Gem of Premonition is an essence gem which allows players to evade traps with only half the cost to their Focus, and also improves their Mind attribute. It is a stronger version of the Slick Gem and a weaker version of the Gem of Foresight.
It can be found in the Outer Courtyard at Dirge, being located in a ceramic urn.
In-game description: "This gem's inner structure does not appear similar to any other essence gem, and there are no records of it ever having been created. Its origin is a mystery, as is the nature of its power. It appears to give the wielder a glimmer of the future, enabling its user to move away from coming harm. It does not remove the danger, but makes danger easier to avoid."
