PoE 3.25 - Quest for a Mirror! (Shard) Part 1*

I've decided to continue my harbinger farming, and want to try to push for a mirror shard drop. At the very least, I hope to be able to gather some data on the drop rate frequency/ratio between mirror shards and fracturing shards or see what sort of ballpark that ratio is in, as I wasn't finding much info on it online.

This farm is consistently profitable just from the harbinger loot, and has a lot of opportunity for little jackpots as well, so it is keeping me well engaged. I am able to run a 10 map set in an hour, and have yet to not get an instance of fracturing shards to drop from a 10 map set. The way I have this set up I am also getting a lot of scarabs and maps/decent amount of T17 maps to convert. Also, just due to the amount of mobs you're gaining on the map you have a good amount of raw/random loot as well - raw divs, fractured items, synth items, div cards, etc, as well as the potential for profitable altar rewards.

No mirror shards yet. The quest continues!
