Secret Art: Meteor

You mark a 30x30ft area and begin summoning a meteor to strike it at the start of your next turn. Those in the area when it lands take Heavy Fire Damage. 

Overcharge: You may spend extra AP on this ability to increase the damage and size of it. For every extra 2 AP spent on it, the size increases by 5ft and the damage increases by your Power. If the Overcharge increases the AP cost to above 4, this ability gains the Setup keyword. You mark the area of this ability when you have finished spending all AP on it and not before. The maximum AP you can spend on this ability is 16 AP.
