So I was thinking that for the sake of realism it should be possible to attack swarms of midges. However in real life attacking swarms of midges goes nowhere. They call forth endless waves of reinforcements from the undergrowth and the shrubbery.
So in game it should be possible to attack swarms of midges just like in real life. Also, if a weapon is equipped, the weapon should lose durability and with or without a weapon equipped the player should gain the debuff "midge mitts" which makes the players hands dirty and slippery. Attacks performed with a weapon equipped while the debuff midge mitts is applied should have a chance of the weapon slipping from your hands and flying several tiles away.
Thank you for your consideration.
