Notes
The bonus from this spell is always less than the bonus from identify, despite being a much higher level spell. (For example, at caster level 40 identify gives +50 to lore checks while legend lore only gives +30.) The advantage of legend lore is its long duration, which can be important when pausing the game isn't an option (as is the case in many multiplayer games) and when lore checks are made in the middle of dialog.
