Memory
A character with this skill has a very good memory. A successful skill roll (5% per rank plus ((KNOW - 15) x 3)) allows the character to dredge up some forgotten tidbit of information or remember, verbatim, the layout of a map that he saw only briefly, etc.

Additionally, all lore rolls (Armor Lore, Artifact Lore, Monster Lore, etc.) are increased by 1% per rank of Memory.
