"We must maintain distance!" Heinz calls out to Catylina.
ooc: JA, I need to know the exact positions (not just distance but also spread) and speed of the enemy in order to use my spells effectively.
The enemy should now be within 50 yards. Heinz casts stone call, catching as many of the enemy as he can in the effect, and then has his horse retreat (double move) - except that he will not retreat past Catylina's position, not wanting to leave her alone to bear the full brunt of the enemy's charge.
As the stones rain down and bash the enemy, the survivors begin to stumble on them as well. (ooc: Stone call creates difficult terrain (lasts 5 rounds): x2 movement cost and no running, should slow down the enemy. The spell affects an 80' diameter circle. There is no save for the damage.)
