Flare Stars

So Haeru is supposed to be able to use Demon magic but he doesn't really know any per se since he's never actually learned any. I'm introducing this as a sort of stopgap generic energy blast thing...

Demon Spell

• Name: Flare Stars
  
• Who Can Use it: Anyone. I'd think having Adept or better Demon Magic would be ideal.
  
• Type: Offensive
  
• Prayer: Unite the omens of war Touketsu!
  
• Effects:A number of orbs of crackling energy are sent forth in a spiraling trajectory. (Double if the prayer is used.) They each have a slightly different energy signature and when they impact something the bursts intermingle and react to create a flux of energy. The explosion that follows acts almost like a pool of microwaves, searing, melting, and lighting objects on fire instead of simply 'exploding' them.
  
• Notes:

• Adept users of Demon Magic would be able to create about 2-3 orbs (4-6 with prayer). Each orb would be about .5 meters in diameter and the the resulting explosion is approximately 4-5 meters in diameter.
  
• Advanced users can create 3-4 (6-8 ) orbs 1 meter in diameter with their explosion totaling about 10-12 meters in diameter.
  
• Master users can create 4-5 (8-10) orbs 2 meters in diameter with an explosion of about 20-25 meters in diameter.
  
• Grandmasters on the other hand can create 6-8 (12-16) orbs 3 meters in diameter with an explosion 40-50 meters in diameter.

Can you give me a range on the explosion radius of each orb as well as the size of the orbs themselves (If they are different with each rank tell me how much bigger they get)

Hmm I'm not strong with precise measurements but do these sound about right?

Approvlified!
