There are multiple cape colors which signify psy ranking. Red Cape: a beginner Psy; they're mostly taught theory at the Academy. Blue Cape: a slightly more advanced Psy; they are novices with little field experience. Blue Capes are barely capable of dealing 3 damage with a Mind Blast. Black Cape: a Psy who was taught at the Academy for several years and passed stringent exams; they have some experience in more advanced Psy abilities like Elemental Blasts and Feedback and are pretty comfortable using basic shields and Mind Blast.
