Diva Skills don't work for this monster.
Here the Z-Sigil won't affect the set or weapon used.
The best weapon for this fight is the Apophis Sword "Shine". Since the Evo only has mediem length a length up sigil will be very helpful.
Sigil 1: [ SnS Up 15 | Beam Slash | Length ]
Sigil 2: [ Element 15 | Element 15 | Element 15 ]
Sigil 3: [ Element 15 | Element 15 | Element 15 ] or [ Element 15 | Duration 12 | Wait Time 17 ]
I'm not entirely sure if Ice Age or crit conversion is better. Safe to say the more you hit the head the better crit conversion becomes. And since the difference is minimal anyway therefore I'd recommend going crit conversion.
You can't bring any items with you.
In the shop I buy a Movement Speed Fruit and 30 Power Crystals. The Fruit is used to get to his spawn point faster to make the intro more consistent.
To get both PD's right at the start be sure to position yourself in the bottom left corner of the square in the ground as seen in the clip. With that positioning the hitbox of the lightning balls should be consistent enough to PD.
This move is super quick and hard to avoid. Its most important to i-frame the initial slam. After that be sure to also avoid his hitbox on the wing when he comes around.
