For one of the season 12 Objective, I have to augment a legendary item in Kanai's Cube. I would like to augment an item for my monk. I'm currently using the Sunwuko Build from icyvines, and it's working pretty well.
I have three questions:
What item should I augment to get the most power? And what gems to go along with it? (most important!)
What level should the legendary gem be before sacrificing it? Level 80?
Can I augment the item to have more than one legendary gem? For example, if I augment with Legendary Gem A, then later augment with Legendary Gem B, would that net me both benefits in that one augmented item?
