Compact Regression

Compact Regression (コムパクト レグレシオン Komupakuto Reguresion) is a form of Caster-type Magic unique to Dragons, according to Scylla.

Description
Compact Regression is a spell unique to Dragons. It allows them to save themselves in times of injury by using all their remaining magical power to transform into a humanoid form. This works as a genuine physical transformation, altering their bodies to be somewhat similar to humans, and it heals their body of wounds. Whether they can transform back to their Dragon state is unknown, which would explain this spell's use as a last resort. Dragons in this state can still use their magic as Dragon Slayer magic, and can also breed with humans. The half-breed offspring in these cases will usually possess Dragon Slayer magic. Momoko Sitri is from a clan of humans that interbred with Dragon's who had used this spell.
