The Fend: if you have a longer weapon than your opponent and it has the fend ability (spears and swords do), you can declare that you are interposing it between you. Once you declare this during your action (and you CAN attack with it while doing so, if you choose), if your target attempts to close with you, you get +2 to hit them and they get -2 to hit you. Unfortunately, due to focusing on them, you are at -2 to defend against any attacks from a different direction.
All-out attack: +2 to hit and damage, -4 to defend against melee attacks and ranged attacks from the direction you're charging.
Impale: with an impaling weapon, when you score a crit you can choose to impale instead. This adds two bonus damage dice instead of just one, but you have to roll a Strength + Weapon skill check (diff 15) or else it gets stuck in them and wrenched out of your hand. Eh, maybe just say they lose their next attack retrieving it.
