How to make an item part 2 in ROW (Revenge of war) Server

This video has no subtitles or explanations, but it is the 2nd step in the previous video. In this video I made a tutorial on how to upgrade defense on a helmet. In the video I made 2x fuser, 4x fuser, and 8x fuser. I started to make a fuser from item A, before from A I bought an item in the Blackmarket from B (which has 1 slot or 2 slots) then I upgraded the item to A. Then the next step is to buy items of the same grade, namely A as many as you need . Then do the same steps as in the video. Note: 1. Try to use a lucky set to find items that have 2 slots 2. Try for the last fuser to have 2 slots before finally sacrificing to the main item, if you have a Socket Puncher you can use it to add a slot to the last fuser.
