Mana Flash
Get into a wide stance and put your arms out to the side so you look like the letter T. Visualize your arms filling with Mana until they can't hold any more. Bring your arms straight up so your fists touch and visualize a block in your wrists and visualize roots growing out of your feet, pulling in more Mana to fill your arms until they begin to shake with power. Bring your arms down to point at your enemy and visualize the blocks in your wrists vanishing so all the Mana in your arms shoots out quickly.

Super Mana Kamehameha
Point one hand to the sky and one to the ground.  Gather air energy from the sky and earth energy from the ground.  Bring the energy inside of your chest and mix it.  Cup your hands for a Kamehameha attack.  Perform a Mana Flame.  Move the mixed to your palms and make a Mana Ball.  Push more and more Mana into the ball and make it bigger.  Launch the ball.  Concentrate on the ball exploding when it hits your target
