Your tools are not

In this game you must attack and parry incoming enemies to defeat them. However, the only way to increase your stats is to equip items with boosts that can lie to you.

 A lie means that it doesn't do anything. You cross out lies to increase your other boosts on the same piece of equipment.

 Attacking enemies will lower there health by your attack value. Parrying enemies allows you to avoid damage next enemy attack and hurt the by your parry value. Careful though there's a chance you can fail to parry.
