For Brew:
dual wield
single wield
for things you already possess natural killer rate for sub a dual wield sub and use set #1
For undead sub pld
for demon sub sam
for arcana sub drk
for drg sub drg
For both sets use lion blinding horn and smiting blow for atmas.
Use killer instinct with the proper pet out for the dual wield situations,
And use the proper circle ability for the single wield situations.
In set #1 the renauds is augmented with +100 tp bonus and goes in the offhand.
in the #2 set the moonshade has mab and tp bonus
in both set the desultor tassets have mab and macc
the demon rings both augmented with mab 3 from tahrongi gold chests.
There are several open slots. These can be filled with specific killer gear if it matches wat your going after. Example: if you were going to brew Bennu you could macro in melaco mittens to your dual wield brew set.
They can also be filled with random Mab augments you might have on gear. Str and Mnd bumps wont effect the damage on your brewed cloudsplitter.
P.S. for primal rend the same concept works just switch out the thunder gorget/belt for soil.
Use TP +100 renauds +2 and tatami for single
and renauds +1 +10% ws dmg/ tp +100 renauds +2 for dual wield.
and switch atmas to atma of the beyond, atma of the smiting blow and atma the ultimate (or hells guardian).
