Edit: found out its too costly to sustain it and no shaped/elder il86 base ever dropped......................

Why Elder Grotto map?

It drop fuse card loyalty pretty easy! Also, it is larger and kinda linear for fast clear using Headhunter. Moreover, it have larger area thus no. of monster in general. And it can use 4 white sextant!

Moreover i follow this guide:

https://www.pathofexile.com/forum/view-thread/2183919

I scour up all t16 guardian and t15 red (not shaped one) maps.
i have 2 shaped t15 map: BOG and BELFRY.
I have 2 shaped t14 map: SEPULCHRE and WASTE POOL.

I mostly cycle between there 5 map clear inc boss, all can drop the only t16 map. Vaal temple seem not possible to drop? And i get its card only...


But i do not:
1. did not chisel my map
2. did not roll 30+ pack size, just run at ~25 pack size or any

I do:

A. I use 4 white sextant for anything it come up around grotto.
B. Alc my map.
C. Beyond every t16 grotto map at Zana option.
D. Pick item at map clear for HH maintain

So far, elder grotto is dropping!
