If this has never been accomplished in the forums, I will be very disappointed, considering the other members who have managed to make it through the other games through Nightmare mode. If someone has, let me know what your strategy was, along with who you used in the attempt. I am obviously trying to Four-Star my Nightmare mode save, from Arenas, to Story, and even the Doom Challenge. I have completed all but the No Switch and No Lives Lost objectives for the Ultimate Weapon, so please let me know when you can.

Strategies:
a. Using Snap Shot's Hydro Arrow over and over again in quick succession, while also dodging the many hazards Kaos sends out. Kaos (Trapped) is used mainly as an assurance that I won't kill Snap Shot while dodging the hazards, and as Kaos attacks are mainly close range, I set his sigils to Magic, that way he can have a continually filled timer. As of now, I have only made it part way through the third phase of the fight, as I don't switch to Kaos fast enough in desperate areas.
b. [None, haven't attempted character yet.]
c. [None, haven't attempted character yet.]
d. Another plan that I have not tested is to set Kaos' sigils to Magic, as stated before, get close to boss Kaos, and spam the Doom Sharks as much as I can. It will almost certainly be slow going, and should only be used in maybe the first and third phases of the fight (The first I have found to take the longest amount of time to accomplish, while the third there isn't much time to hit Kaos before he begins another bout of attacks. The second phase usually yields enough time to hit him).
Any and all suggestions will be appreciated.
