  1. Something that worked remarkably well for me was Persona that drained or nulled all his attacks, then spam Charge -> Myraid Slashes w/ Yoshitsune. Worked like a charm for me.

  2. Another really easy strat that will pretty much let you carry the fight without ever having to swap from Joker is have the combination of these personas Metatron (Drains Nuke and Psi nulls wind + learns debilitate) Youshitsune (Nuls thunder + Hight attack power with Tech adept), (Alice Drains curse magic), Mara (drains fire) Black Frost(Drains Ice). By this point in the game you will have access all of these personas as you can’t even fight reaper without beating them. With this set up all you need to do is keep attacking reaper non-stop, you have a 2 second window when he is casting so all you have to do is swap to the persona that nulls/drains the element he is casting before the spell hits (refresh debilitate with metatron when he is casting nuke or psi). Since he casts concentrate a lot he will often over heal you and or do no damage so you can continue to attack uninterrupted. The only moves to avoid is megidolan and his gun attack neither of which he should use often. Once you get the timing down he is remarkably easy

  3. Set his ass on fire and spam wind skills. All you need is Ann and Morgana. I did heat riser and debilitate to speed up the process. Killed him in like 2 minutes, only got hit once.
