I'm playing SSF btw

I need a stupid T4 unique that I haven't managed to drop (I did drop the ONLY OTHER UNIQUE WITH THE SAME BASE THANK YOU GGG -well at least this means that I can guarantee the one I need if I get an Ancient orb, right?- edit: no, Ancient Orb keeps class and ignores base, so I can vendor the one I dropped OK) or chance.

I missed a few years of PoE, so reading around it seems like trying Gwennen gambling is (or was) a good way to farm T1-T0, so I guess it should work for lower tiers as well? But is there a better way that you can suggest?

I'm at my wits' end, since I'm level 87 and I haven't managed to get it yet, absolutely my fault I know, but if I can't get it "soon" I will probably migrate to Trade league and buy it for 3c lol
