Use Spiral to keep the 3 at bay while charging DTE. Once you have it fully charged, kill them all with it. When the final Lust appears, kill him VERY slowly (try and keep your style up; free-ride and taunts help a lot). Try and get yourself a full DT bar - it is very important you do so to prepare for the battle in the next room. (Yes this is a copy-paste from mission 4)

This is not as easy as it sounds. Make sure you are charging DTE at all times. As the battle begins, drop directly down to the door at the top of the steps. STAY AT THE CENTER OF THE SCREEN AT ALL TIMES. Pull out Nevan and Combo 2 the first Enigma to death. Once it's down, a Sloth will appear in the middle of the platform. Perform a launcher, then a Real Impact and DTE at the end of it (this will hit him and the Sloth teleporting around you).

Once that's done, proceed to the left of the screen and Nevan Combo 2 the Enigma to death. The Sloth may attack you in the middle of this, so jump as he attacks and perform Air Play before continuing with combo 2. After that, proceed to the other side of the room and do the same to the other Enigma. Once he's down, move back slightly (about 2 meters/6 feet) and wait for the next Enigma to fall, then immediately DTE it.

Now all you should have left are 2 Enigmas and 1 Sloth. Try luring the Enigmas into the tunnel towards the door on the bottom floor or the steps. Once they are trapped, keep the pressure on them with Nevan Combo 2 (while Air Playing if the Sloth is about to attack). Once finished, kill the sloth as you see fit.

Now here is some fun for you. Stand in the center of the elevator and prepare a “Volcano”. When the first 4 Prides fall, hit them with it, then taunt for good measure. Do this for all 4 waves. You probably won’t hit all of them for the last wave, so K Ann or Spiral the one you miss.

Set up - Royalguard with E & I

If you feel you can handle RG well enough to jump parry A LOT, feel free to use this strategy. It is pretty simple - all you have to do is jump parry the first brother's Dash & Dive attack and when the other brother comes along, jump Release (+ DTE) his dive attack. This results in equally enormous damage to both brothers, but do not hesitate. Immediately run back into the middle of the 2 brothers or you will find a very subtle Stinger or Dive attack heading your way (by subtle I mean without a sound cue)

For the actual charging of your DT, target Rudra (blue) and shoot 1-2 times with E & I. This will make him guard for a short time before retaliating with a rather poor and easily traceable uppercut. Time your jump with the attack and air parry it. Typically, he will hit his brother, hence stopping any attack coming from behind. The downside to this is that it will uneven the damage each brother is taking. To slightly get around this, once they start preparing for a team attack, get in as many E & I shots as you can at Agni (red).

This tactic does not change throughout the game but a few words of warning: if while parrying Rudras attack Agni decides to attack first, DO NOT stick to the usual plan. Instead, clearly jump evade until Rudra starts making the first strikes. This may make the battle slightly more tedious but it is a lot safer than risking getting hit at such a late stage of the level.
