This one is a bit more complicated since I'm once again not sure what is the best way to go. I have three options in mind:
1st option is not playing SW, which the current record also doesn't use, on the other hand playing SW is definitely possible and is also definitely more damage. Therefore set 2 and 3 will use SW one with Rush Up purely for convenience since rarely you can run out of stamina in the fight and the other with Ice Age for optimal damage. I will have to split some of the sections into two because of this and I hope its still understandable.
If you run SW the best weapon is either Purge Frostsword "Shine" or Nepa Icecutter "Shine" regardless of if you have the Z-Sigil.
If you don't run SW the best choice with the Z-Sigil is still an Ice Evo but without it, the best choice becomes the B.Z. Prayer Enrapture Sword "Encore".
In my opinion you should run very long with the prayer and long with the evo. Length is really good in this fight.
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 ]
No SW:
Z-Sigil
No Z-Sigil
With SW
Use the Power Crystals first. During the first nuke use the Lightningrod for I-frames and to cancel the animation of putting the poison crystals in your weapon.
If you play SW use the potion during the intro nuke.
Zino likes to turn around after most attacks which will stagger you to the ground. To avoid this your best option is to use Adv. Slash for the super armor. You could also delay your evade slash but this will be less damage. Mastering this is key for a fast clear time.
Since Zino is difficult to poison the current strat is to use Power crystals first and then swith to poison once he nukes. By then you should have furious which will make the poison easier. To do this use a lightningrod to cancel the animation and get i-frames.
This is a move where if you position right next to his legs his turnaround will always miss you, so you can get a beamslash in instead of an Adv. Slash.
