Question on weapon choices

Would a 3 lined King Cent (Avg 74 WA clean) or a 2 lined Reverse/Timeless Equinox (Avg 84 WA clean) be better?

Assuming you have money to burn on cubes, the Cent is much better.

Alright. Will start looking for some decent 3 lined King Cents then. What potentials should I be looking for when cubing? I intend to use 100 cubes.

Things like x% Total Damage, x% Boss Damage, Ignore x% of a Monsters Phys/Magic Defense (it will say ATT, but it's really ignoring some PDRate or MDRate), x% Str, x% Attack...

I'm pretty sure those are all the most useful modifiers. I would go for Total Damage/Boss Damage/Ignore Def over %Str or %Attack, because %Str comes on most other equips and because %Attack doesn't count certain sources of Attack.

If you don't get to Unique, +Attack is also a nice potential.

and because %Attack doesn't count certain sources of Attack.

I totaly agree with your top picks for potential but just so you know, %Attack stacks with buffs now (i.e. rage). I am fairly certain that %attack also stacks with "use" buffs (i.e. apples) but i can not confirm.

The sources of raw attack that aren't included are stars. Probably bullets too but I never heard anything about it. Either way, op has nothing to worry about regarding those two factors.

If your going to invest 100 cubes into the cent look for somthing better than a 74 att cent. try using the maker skill if you have it. 82 w.att clean is possible on a cent which will net you 127 att if you use 9 pinks.
