Yeah, it was just an example. Maybe make some new items like... "No EXP Pill" while this item is in your bag, you won't gain any exp towards level that can be bought for critt as an alternative to anthem.
Although about the accessory shop item... It's pretty useless when you come to think of it because 2 AC start crest beats almost any other ring in the game. Soon most people will have star crests... so they won't need the accessory shop unless it has something better.
