Mage Tifa defeats Alexander in 20 seconds (Dynamic, Full Might) [FF7 Rebirth]

Another funny mage Tifa speedkill. Again, like Titan, this was in my summons speedkill montage but this is a cleaner run (though I didn't have to go into the tactical menu to cast Thundaga, oops).
Killing Alexander before he teleports here is actually pretty annoying.
I'm pretty sure the loadout is:
Crystal Gloves: Enhanced Elements, Atk Power +20, Atk Power +20, Magic Atk Power +20
Genji Gloves
Elemental-Lightning, Swiftcast-Lightning, Magic Focus-Lightning, Phoenix
First Strike-HP MP Swap, Str Up-Magic Up, ATB Boost-Enemy Skill, ATB Stagger-Skill Master

When I try this in hard mode it just comes up saying normal at the end. I select full might too.

Yeah, hard defaults to normal, while dynamic sets it to dynamic. I don't think it has a big difference outside of Dynamic having a slightly higher HP total though
