Broken Bottles
You've been around the block and know when a scrap is brewing. You're able to pick out the best makeshift weaponry in your environment. At 3rd level you gain proficiency with improvised weapons and they can be used for your Brawler features in place of unarmed attacks. When you would miss with an attack with an improvised weapon, not due to a creature moving out of reach from the attack, it shatters. Your improvised weapon breaks, but roll any Combo die you would have lost. You deal that much Force damage to the target. This damage bypasses damage reduction. If you did not have a Combo die you gain one for the purpose of triggering this effect.
