So I'm starting to play through End Game Insane mode. I know next to nothing concerning item fusing. I tried it a little before the wipe and it made no darn sense to me. At what point in the game does item fusing become important? As of now, I just play the next level and pickup up better items so I don't see the real value in fusing items yet if a couple of levels later I can just pickup better stuff. Is there a guide online that explains the fusing process? Does using legendary gear to fuse have better results than plain gear? Should they be the same type of gear? Thx
