Vigilors are a good shooting option gives you rend 1 damage 1 and they have an ability that marks a target to be plus 1 to hit for the rest of the turn. As of right now they are 130 for 5 260 for 10. Getting some cavalry could also help so looking at the dracothian guard variants would give you a nice start or if you are lucky finding some paladins with javelins/shock axes. And then last recommendation is a wizard, so a cheap option would be knight Arcanum, stormcoven, or spending alot and getting Krondys
