( Erin's POV )
Erin felt a lot stronger after completing his floor10 promotion, as his body no longer felt dizzy when he performed sudden movements.
Throughout his life, Erin had been suffering from a mild case of Vertigo, which made his head spin a bit from sudden movements, which was why he could never jump out of bed after 8 hours of sleeping and always needed to get up slowly.
When he began physically training his body after joining the university, his condition did get a bit better, however, only to the point where it was still just a minor discomfort, but still mildly noticeable.
However, after his tier 1 promotion, Erin no longer felt any physical discomfort from sudden movements, while the flow of mana through his body also felt a lot smoother.
