Taken from wiki: “The Ley-Energy Matter Converter is an item that lets you trade Currencies you earn in the Magus Falls maps for other currencies, or different other items, like Karmic Crafting Bag or Bag of Educational Supplies. You can buy only one item per Tab per day. A counter on the top right of the vendor window tells you, if you have a remaining trade for this day. Currently, tab unlocks reset daily, and it’s unkown whether or not this is a bug or intended.”
So the question is, is this intended? It currently feels like a trap investment and I’m sure %80 of the players(that have this item) have done the mistake of unlocking other tabs. A clarification might be needed for the truth behind this item.
