Mortar Charge
Load the blunderbuss with heavy canisters. For the next 15s or 3 shots, shots will no longer fire multiple pellets but instead will fire a heavy, fast diving, mortar-style canister that causes a tall explosion upon impact, dealing 100% weapon damage in a 3m area.
If the target is 10m away or further, they will take 35% increased damage from the mortar.
