Combo Finisher

I have lately came across old players who didn't knew what a combo was, so maybe we need to make sure we all know about this.

The four types of finishers each apply their effects differently:

• Blast finishers apply their effect to all foes or allies in the area where the blast occurred with radius 360.
  
• Leap finishers apply their effect either to the target foe or to yourself.
  
• Projectile finishers apply their effect either to the target foe or to allies adjacent to the target.
  
• Whirl finishers cause multiple projectiles to be launched in random directions.
