Increases fire defence.
Voyage out from the lantern until you come to this distinct green lamppost. Just ahead is a hill that runs on the left side of the valley. Follow it up and drop to a second hill; follow this up to find the Run on a corpse.
Clear Deep Sea
Increases slow poison resistance.
At the bottom of the Nightmare Frontier is a large poison lake. Look for this little passageway you can enter, then follow it uphill. You'll find a boulder-throwing enemy and the Rune here.
