Maneuvers

At the start of every turn Oak gains two 1d8 superiority dice for a maximum of two. Oak can use both of his dice within a single turn. These dice can be used for any of the maneuvers below.
Disarming Attack - When you hit a creature with a weapon attack, you can expend one superiority die to attempt to disarm the target, forcing it to drop one item of your choice that it's holding. You add the superiority die to the attack's damage roll, and the target must make a Strength saving throw. On a failed save, it drops the object you choose. The object lands at its feet.
Brace - When a creature you can see moves into the reach you have with the melee weapon you're wielding, you can use your reaction to expend one superiority die and make one attack against the creature, using that weapon. If the attack hits, add the superiority die to the weapon's damage roll.
Parry - When another creature damages you with a melee attack, you can use your reaction and expend one superiority die to reduce the damage by the number you roll on your superiority die + your Dexterity modifier.
Precision Attack - When you make a weapon attack roll against a creature, you can expend one superiority die to add it to the roll. You can use this maneuver before or after making the attack roll, but before any effects of the attack are applied.
Riposte - When a creature misses you with a melee attack, you can use your reaction and expend one superiority die to make a melee weapon attack against the creature. If you hit, you add the superiority die to the attack's damage roll.
Evasive Footwork - When you move, you can expend one superiority die, rolling the die and adding the number rolled to your AC until you stop moving.
