In Mythras "Breaking the Habit" scenario, there's an opponent armed with javelins hanging back behind the shield wall formed by other four enemies. His tactics are, according to the scenario:
Harassing characters hanging back, pinning shields or providing close support to his friends against e.g. characters using Very Long reach weapons. If anyone threatens to break through the line, a readied javelin will be waiting for them.
At the start of the scenario the PCs are a few meters away of the shield wall. If the javelin thrower gains the initiative and wants to throw a javelin at one of the PCs... Are there rules addressing that case? I found rules to throw into a melee, but the PCs would not be engaged with the infantrymen forming the shield wall yet, so I guess it doesn't apply.
I guess it could be an attack roll with one or two steps of added difficulty, but I'd like to know if there's an specific rule that can be applied to this situation.
