It is to keep him stablezed in a mission, there is a chapter where the dog take it away and taegun comes out in a bad shape barely holding up, so he needs it
Well I remember I read that chapter but that wasn't much different from how he always is when he needs guiding you know? So is it even helping? Lol
it was supposed to increase the englergy he can expend, the reason he came out less in control than usual was bc the dog yoinked the charge, but he didn't know and was more liberal with his powers
He put it on him cause it's supposed to show his status condition right? Or was it supposed to give like minor guiding? It's just always red but I swore at one point it was green right? What's the point in the bracelet if he's getting proper guiding now?
