"Alright!" I smile, happy with my students honesty! "Now, lets take a look at a B-Rank technique. So, if you split a B-Rank into 2 projectiles, you end up with two C-Rank projectiles. Those two C-Rank projectiles, should the be combined together again, will always total up to the original B-Rank damage. However individually they are weaker but combined they are equal. Now, lets look at that with the A-Rank technique. If you produce 2 projectiles from an A-Rank then each projectile is B-Rank. 4 would produce C-Rank level in strength. And 8 would produce D-Rank level in strength. Think of factors. No matter what they will always end up totaling back up to their original level in strength."
