Arcane Knowledge represents the general knowledge of the character about objects and places of lore or other importance. It is useful for one character in the party to have this ability, giving them a high chance of knowing about places they arrive in.
While intelligence can help with Arcane Knowledge checks, the first level in Arcane Knowledge is worth 20 intelligence and further levels are worth at least several points of intelligence. As a minor ability it is a worthy investment.
Clerics, Druids, Magic-users, Bards, Battle Mages, Illusionists, Necromancers, and Priests can learn Arcane Knowledge, but it is common cross-class and as a backstory ability.
For example of Arcane Knowledge usage, see the installments of the Shrine of Zemail.
