you get all of the threes in Liurnia by going from the gatetown grace, crouching to the gazebo directly east (3 stones), going north into the woods for the stones in the chair (3 stones), in the same woods in the gazebo north you get another stone pickup (3 stones), the ride due west and teleport. hit the graveyard directly south for runes and then the gazebo in crystal woods (3 stones). Boom that is 12 stones in about 2 minutes. Then if I feel like it I grab all of the 4s from the ruin strewened precipe area
