1. When you use a raid muhbis to make a non visible item, is it a guaranteed 5 luck? 2. If it is not guaranteed, has there been discussion as to the reasons why it is not? 3. If your raid muhbis non visible is 4 luck (for example), is the only way to increase it to 5 luck is to fuse it with the exact same item? Which means using another raid muhbis on an item to fuse for just one luck? Thanks in advance for the responses.
