vaults of atziri unique map ssf

So I know i'm ssf but i'm literally halfway through 99, over 1.2 mill mob kills, over 2ooo chances on vaal pyramid map, tons of kirac map rerolls, rin in fortification and not 1 single vaults of atziri unique map. Please take a look at this, last map i need for atlas completion.

There is nothing to look at. It's just RNG.

Not 99, but compared to how it was thrown at us over the last few leagues i also feel really confused about how it just wont show up. Ive seen kirac show me every other unique map at least 3 times, even the doryani one, but that vault just dosen't seem to exist.

I've dropped 3 so far from normal farming with 100+ rarity. Try a map farming strategy with shrines and map scarabs if you have them with IIR. T17 or T16.5 with boosted map chance (if able) with favorited Vaal Pyramid.

If you want go further, there's an option to throw mappers at maps with chance at unique map div cards. Maze, Synth maps, etc. But probably overkill if doing above strat.
