What are most archmages using as their

I'm not an A/M, but I think I have a general idea.
First of all, most people of any job nowadays are statless, since getting enough secondary stat to equip a endgame weapon is relatively easy.

I know very few LUKless mages now, most are low LUK if anything because everyone's got a tier 3 overall and stuff for the most %INT.
What matters is what OP's able to afford.

For most of the equips that are just armor, you're going to want to aim for %INT. I've been told that for your weapon %MATK works out better, but since there's enough different things you can get on your weapon that changes what kind of damage you do that's really down to personal preference now. Around Bera right now most of the mages I see are running around with a reverse/timeless overall, czak/targa [or reg zak hat if you're lazy like me], and 90+ gloves and shoe. That way you can cube it for the best stats, since 3x6%INT is way better than 3x3%INT off a bathrobe. Since you said you played before BB I'm going to blindly assume you're familiar with the elemental weapons and probably have one even if it's a lower level - that's definetly the thing to stick with, far better than any of the standard weapons for a A/M.
In terms of getting the LUK, if you're gonna try to stay as low as possible, I'd say get one of the hats scrolled for LUK [maybe with %LUK if it helps more, up to you] and a HTP if you can. That should knock out...27+however good a scrolled hat you can get, I've seen ranging 25-3x for the hats so you can get around 50LUK knocked out just from that. I'm blanking on if there's shield LUK scrolls, that would be another thing you can do [somehow I don't think these exist though, I can't remember]. Obviously remember that you can substitute around equips as necessary.
