【Final Fantasy VII Rebirth】Brutal Challenge 6: Rulers of the Outer Worlds (Cloud/Yuffie/Barrot) 

Personal Notes/Tips -I have not touched Hard Mode before clearing this (because i am stupid =w=), so doing that first instead can make this a tad bit easier with the extra stats. -The strat revolves around having Cloud spam his Lv3 Limit Break. -Enhanced Expeditionary Medal and Limit Siphon Materia are the two most important things to have. -It's also crucial to have your party carry any ATB and LB regen abilities/materia if you're going for this strat. -Each member should also have Elemental+Fire for the some Fire resistance, will be helpful for Round 1, 4 and 5. -Additionally, having one member carry the Limit Booster accessory was also quite game changing for Sephiroth as it lets Cloud get into his LB much sooner than having to drag out phase 1 fight longer than needed. -I went with Yuffie and Barrot as support most specifically for Gilgamesh and Sephiroth as having ranged attacks allows them to spread out more to avoid any collateral damage while also having some space (and time) between the boss as they approach each one. 00:00 - Round 1 -Straight forward stage, must focus on Kujata first before Phoenix as it'll take no damage while tethered. Upon Kujata's first defeat, I would personally focus on taking out Phoenix first just to avoid it from possibly using its Rebirth Flame ability again. 07:08 - Round 2 -Easiest stage imo with this strat, up to you on who you take out first as Cloud's LB will likely be hitting both targets anyway. I went with Titan since he's quicker to defeat. 11:40 - Round 3 -For Odin, a REALLY quick way to pressure him is by applying Bio and using Yuffie's Doppleganger+Windstorm. -Upon his first stagger, I would personally advise saving Cloud's 2nd LB for Alexander instead once Odin vanish so that you can finish off Alexander in a single rotation (meaning you can also ignore the Light Pillars). 17:32 - Round 4 -Barrier isn't really needed for the whole fight other than his Ultimate Illusion if you're unable to stagger Gilgamesh in time. I like to use it in the beginning as I'm settting up. It also helps to conserve MP for Sephiroth where you'll really need quick Heal and Barrier up at all time. -Keep your party distanced from each other and focus mostly on Yuffie and Barrot for ranged attacks to build ATB and LB. For Cloud, stick to sword waves if you want to play safe. -Dispel also works on Gilgalmesh when he get full buffed, helpful but not super necessary. 25:48 - Round 5 -Same idea as Gilgamesh, keep your party distanced from each other and focus mostly on Yuffie and Barrot for ranged attacks to build ATB and LB. For Cloud, stick to sword waves if you want to play safe. -Barrier is your best friend here. Sephiroth will be spamming his Octoslash in his first phase and getting hit by it can easily take you out without it, so try to always keep it up. -Additionally, getting hit by his Octoslash is also not necessarily a bad thing either as you'll be building LB from those hits, but just be sure to ALWAYS have some ATB available for immediate healing after. -Once you reach Phase 2 (half HP), then he'll stop spamming Octoslash significantly less and turn to elemental affinity, lots easier to deal with. Fortunately, the first elemental he'll change to is Fire which you should have resistance too thanks to the Elemental materia, so (cautiously) go ham. 33:34 - Setup Also, random side note for those completing this before starting Hard Mode. Following the same strat, have another teammate equip Gotterdammerung rather than Cloud as he'll continue to hold Enhanced Expeditionary Medal. With Limit Siphon, he'll be able to immediately use his Lv3 LB at the start of every fight.
