NO T17 MAP DROPS

I have 2 voidstones. I am running t16 maps, some of them corrupted, spme not. I had 2 t17 maps drop a couple days ago, but none since in maybe 30 maps. Am I just having bad luck?

You need 4 voidstones. The drop chance is quite low with only two.

Right, according to the POE wiki, with one voidstone .4% to drop a t17, with two 1.6%, with three 3.6%, with 4 6.4%. So, I hear you. Four voidstones will increase my chances considerably, but 1.6% is not zero, and I've farmed well over 100 t16 maps with no T17s dropping. And, like I said, I had a couple drop the other day, but now zero for many many maps. Is there something else I might be overlooking, something I might have changed?

Unallocate the Singular Focus keystone if you have it. I suspect that can interfere with some t17 returns. https://www.poewiki.net/wiki/Singular_Focus
