Portions of the ground are quite solid, while others are soft and wet. Trees, vines, and shrubs are quite abundant and there often are unusual specimens with odd colorations or outlines.
Granted, the farther you move away from the main group, the harder it will be for the stationary Aeranduil to see the exact spot for aiming -- after about 100', he will be unable to see anything specific.
Is Aeranduil going to pursue the scorrow as well? (i.e. move towards Ipshivi and Morika) If so, how far is the subgroup planning on the pursuit (either in rounds or distance)?
