Turning Invisible?

From what i have seen there are only 3 ways to turn invisible, semi-invisible. 1:literally invisible: Shenks lagg after you kill him. 2: semi invisible: Nats full set on a sin and 3: semi-invisible: the assassin move fade. Oh and to make ur items turn invisible put them on while having enough strength from items to wear them then take the items that give you the strength off, the item that needed that item(s) for strength will still be on and will still work/function but will be invisible, only u can see it in ur inv.
