Amplification Summoning Technique

This is a summoning technique that bestows a special ability upon a summoned creature once predefined condition has been met.

Overview
While it is unknown how often Pain modified any of his other summoned creatures with this technique, he has granted his dog summon a number of abilities that increased both its offensive potential and overall resilience. For instance, having set the condition to multiply when being dealt damage, the canine could divide into more identical beasts and increase its combat capability. It seems that multiple abilities can be granted, as the beasts can recombine if needed, having one body carry the heads of however many additional beasts were created. It was also given the ability to split independent of damage, grow wings that enable flight, shape-shift to avoid capture, as well as the ability to self-destruct.
