[Wartune - Time Vortex] Sub-1,33M Final Reaper

Still not even an unbeatable (theoretical) world record!! But practically as far as I can and am willing to go for this boss, unless future power creep.

The build
No fused Sylphs allowed!! (same old rule)
Lvl 1 Meteoric Assault (20% stun chance) for buff-skip
Tattoos: +Endurance & -Defense to minimize BR
Sylph - Apollo (+0 Sepulcrum stats): Double -15% dmg taken and Blessed Electro being the key to survival
Cutie - Undead Gladiator: Lvl 6 Rejuvenation & lvl 7 Mass Healing, being essential regen besides active healing skills
Paralyzing Dagger: Essential passive-dmg reduction, triggered on receiving damage, 2/2 green deer and 2/2 green eagle
Goddess - Asteria: Kept at lvl 1 with devotion lvl 2's -5% dmg taken being key
Mounts: Three login prize mounts, IceFyre (lowest mount that give +110% speed & fly ability) and Black Meow Queen (cause Life Like Meowws)
DGC skills: Full-flame accumulation skills, Dragon Spell, Tenacity, Undead, Icicle (RNG-removing the phase 2 +40% DMG buff)
Potencies: Rules of Survival (even less BR), Essence Leech (Sylph camping & Awakening-flicking)
Astros: Top-4 best, Enhanced Regeneration, Enhanced Deflection (good dmg for my build)
Pacts: Absorption, Bleed Res (not sure if works or not), Reflection (main dmg source)
Dragon Soul: Lvl 7 for %-based DEF boost, not going lvl 8
