The members of the crossing group takes what defensive measures they can (Prone, Shield Cover, etc.) as they communicate amongst themselves.
The shooter sees the targets clearly. The druid shapeshifter is down. They are positioned in two range groups and trying to defend against arrows. No movement yet beyond the Alijanian sprinting forward before dropping prone.
Terrain Notes: The flood plain, considered Difficult Terrain - At its most stable, it is grass-covered soggy ground that collapses under any weight, causing walkers feet to sink into mud. At its lower dips, there is standing water with the muddy ground beneath. Water levels vary from ankle to shin deep. In this area, there are no dips in the ground that put water up to knee deep. Off to the left (west), the ground does slope lower again, eventually allowing for a pond area that likely starts shallow and increases depth further west.
Range Notes: It has been brought up, accurately, that the crossing group is currently in Long Range for a longbow. Normal Range for longbow is 150 feet. So that means shots should be taken from Disadvantage until when/if the Range changes. That truth exposes what probably was a bad ruling on my part. I set the original Range and spacing of the first shot, not really in reference to longbow range, but instead by placing the crossers roughly in a middle distance of the crossing ground. Simush may have decided to wait longer and let his targets get within normal Range. On the other hand, the crossers would have been that much closer and have a shortened distance/time if they decide to assault. I plunged in without covering all of those things in questions, but we are where we are.
Ruling: I'm not going to go back now and retcon Range/Distance, but also not going to retcon Maeriks getting shot and put down. Things stay as they are. This means that at the moment, at current positions, no matter if the crossing team is Dodging, Prone, or not, then Longbow shots are made at Disadvantage. In coming rounds obviously, both crossers and shooters may change Range/Distance to affect impacts.
Horse notes: As mentioned above or in Admin I think, the shooter is not on horseback at the moment. Sizhen spotted the horse and identified it as "further up the hill and right."
