Immediately after the room in which you must move the statue of your father down the hall, you will have your second chariot race. At the end of the race you will run into the sand enemy that you saw in the earlier intermission sequence. His brother will come with his sword and surround you in a ring of fire. Run towards the one with the sword and slash at him with your dagger. He will block it, and after a little bit his brother will slam his axe into the ground. Roll to the side to dodge it, and his axe will become stuck in the ground. Vault over him while his brother with the sword tries to slash at you. If done correctly, you will trigger a speed kill scene where you slash them both down to half health. You must try to repeat this process. When the brother with the axe jumps towards you, roll to the side and get away from him. Only go for the one with the sword. If you fail a speed kill you will be knocked to the ground and will lose a lot of health. If you find yourself on the ground, do not try to attack coming up; just roll away to the side.
