We get what we paid for.This Lv50 Madusias750 skell, I can't open its slots cause they cost a whopping 40,000 storage miranium. And it STILL vastly surpassed my, once blue skell, now it's a red skell for Elma cause she's my favorite ally in the game. That skell has a looooooot of open slots by L's shop. Dragon's Maw's a Lv50 exclusive skell art I think.
