There are a lot of items that have had different stats before patch and became the same thing with different names after the major balance patch. For example, before the patch I made a Guardian Necklace and a Superior Guardian Necklace that now give the same Magic Defense. Also, there are 4 different rifles that have the same Physical Attack as the Practice Musket that you get from the NPC: Practice Musket = Musket = Standard Musket = Superior Musket = Yorgis Musket.
There are probably a lot more items, which I want people to report here if they can.
Also, as a suggestion for any IMC employee reading this, please add some basic 315 weapons, not all people are enthusiasts that have the time to spend on making Purple or Orange 315 weapons and equipment. Give us “casuals” colorless or Blue level 315 weapons and equipment. I have 4 archers level 300+ that use level 220 weapons (Vienie Musket, Didel Grand Cross, Hunting Wreech Bow and Chura).
