You have three varieties of blast you can fire. The moment you fire a power you'll be able to set the specifics, assuming any need to be set. For example, if you fired the Gravity Shaker power, you'd be able to choose what gravity it applied over it's area of effect once it hit. While the following descriptions mention Tier-1 level powers, it's really saying any power that could be classified as a Tier-1 power. The first variety fires a random Tier-1 level Blaster or Shaker power at the target. The second fires a random Tier-1 level Striker power at the target. The third gives the target a random Tier-1 Thinker or Master power. This lasts for 3 minutes.
