So here's an idea: A backwards movement sword. Name: Hook Barb. The sword, when it makes contact, brings an enemy towards you. Damage is piercing, and it's a 3*. It has a 3 swing combo. Each swing of the combo causes you to move backwards a bit. The first two swings do around 70 damage, and the last does 90. It kind of looks like a pine tree on a handle, but with sharper points. The charge swing would fling the enemy way back, where another knight could be waiting with a different weapon to finish it off. It could spawn a strategy where the hook barb user moves ahead and flings enemies into the rest of the group waiting behind them...
And now I wait for the trolls to come and say that it'll ruin the mechanics of swords...
