Destroying Alchemy Materials

You'll find a lot of otherwise useless items from monsters with the new patch.
These items can be destroyed in exchange for alchemy and attribute stones.

~~~How to use~~~
-Press A to bring up the action window. right click the alchemy icon
-Press the item enhance tab to bring up the item enhance window
-On the left, put the items that do the destroying (void rondo, destroy rondo)
-On the right, place the useless items
-Press fuse

~~~Stuff to Remember~~~
-Void Rondos are used on the useless items dropped by monsters
-Destroyer rondos are used on equipment items which will yield significantly
higher element turnouts than the useless items.
-Void rondos and destroyer rondos can be purchased at grocery stores.
-There must be sufficient inventory slots in order to destroy useless items
-If you plan on using the new alchemy, keep the elements in your inventory and
keep the tablets in your storage. You will always be making more elements, and
since the stacks of elements go so high, you won't have to worry about it,
however, the tablets come in all shapes and sizes, and since they appear so
randomly you won't have to return to town as often as you would if you were to
keep your elements in the storage instead.
