A variety of ancient abyssite that harbors arcane powers. The bearer will more readily recognize the weaknesses of Abyssean fiends when faced in battle.

Reward for completing the quest Emissaries of God.

When fighting an Abyssean Notorious Monster, this abyssite will occasionally give the player a message corresponding to a particular weakness trigger when using a weapon skill or a spell.

• Message received for yellow/green weakness hints: "The fiend appears vulnerable to <element> elemental magic!"
• Message received for red weakness hints: "The fiend appears vulnerable to <element> elemental based weapon skills!"
• Message received for blue weakness hints: "The fiend appears vulnerable to <weapon type i.e polearm, dagger, etc> weapon skills!"

You can receive a message from any spell or weaponskill used against a mob as long as it's one of the proc spells/weaponskills. Receiving the message is not guaranteed and it may take a few spells/weaponskills to receive the hint.

You may also receive the message if you use a proc AOE weaponskill (such as Cyclone) on a different target, if it also hits the NM. Also, if an AOE weaponskill hits 2 (or more) NMs at the same time, you may get the hint for each of those NMs simultaneously, although you will not know which NM each hint is for.
