So apparently my original post is far too long so all edits and add-ons will be tracked here from now on. EDIT: Just so people know, you only get ONE chest looting per chest per week. You cannot double dip for double the chest loot. Once per week per chest is all you get, you greedy little hooligans! EDIT: During the Templar fight, Fanatics will not sacrifice themselves to the confluxes, but they will rush you and, like the Supplicants during the fight with Atheon, they will explode on you. Difference is, they will explode their goopy goop all over you. You will need to clean yourself up. EDIT: Strategies for tackling Hard Mode will vary. There will be better strategies for everyone and everyone has a different perspective on this fight. If you think my guide is just not working for you, try something new! Every person is different and each playstyle and team-comp will lend itself to different strategy. EDIT: PLEASE CONTRIBUTE IF YOU DISAGREE! Do not just say I have no idea what I am talking about without sharing your own experience on this matter. EDIT: Check the walls in the Templar arena after the fight. There is a hole in the wall that will lead you to two of the three chests that I have found within the vault other than the first "How could you possibly miss me?" chest.
