First things first, you need to turn off all weapons in the main menu, by clicking each weapon with a green box around it, then clicking "disable" at the lower right side of the menu. after that, chose a tomb or arena. once you've done that, how do you deal damage to enemies? Sure you can punch, slap, and tear enemies, but that's kind of time consuming. What you are going to want to do, is look on the floor of the dungeon, you will find large loose bricks, these bricks are the second most powerful weapon in Battle Talent if used correctly. once you have picked one of these bricks up(manually, as you are unable to recall them) you can now start your killing spree. with this brick, aim for the heads of your opponents, as this will do the most damage(100-400 per hit).
