A possible easy solution for the chievo/trophy.

You need to have crafted the grapeshot bomb (doesn't need to be the enhanced version), go to this place and choose to fight the bandits (choose the "Actually see several monsters..." dialogue option). Once the fight starts, quickly make a jump back to get a bit far from the bandits and therefore, away from the blast radius of the grapeshot, and then throw a grapeshot right in the middle of all the bandits. Most of them, (or all) should blow up in pieces.
