Corestone Drops. Mechanics? Improve Rate

[Jor-Mun-Gandr]

Does kill order matter? Critical hit? Luck stat?

Is there anyway to improve the drop rate?

I keep hearing that Luck affects drop rates from various sources (mostly Reddit), but I haven't confirmed that. Anecdotally, I feel like it's marginally faster when I equip a +luck ability, but not by much, so who knows.

If you have minus luck items does Hinna live?

Putting Morley in Nightblade class and equipping Luck+ and Luck, I have 703 Luck.

I have been collecting Evil Sword and Mechanical Golem corestones but no Eye Spy and it has been hours. Tatoh Temple is empty except for one group of

2 Mechanical Golems --- 8
2 Evil Swords ------------ 6
1 Eye Spy ---------------- 0

Finally got Eye Spy corestone. Just in case it matters: 3rd enemy defeated.

I tried the 3rd enemy defeated strategy on Frost Dragon in Wendel Temple below the first Meridian. Success.

Speed likely is a factor. I think the best way to get Shadow Zero-One Corestone is to turn the ringer into Shadow Zero-One and then class strike.

I also tried the luck stacking, but it didn't seem to work. Feels just random. I used class strikes (reload if no drop) and it worked okey. No Idea if it increases the drop rate but it made the process faster.
Got at least one core stone from every pre-postgame enemy ... except for the Polter Box and Kaiser Mimic. I tried for hours to get one for Kaiser Mimic, but no drop at all. Lizardon was also a bit tricky because you need to wait for it to change from Tanpole (and they die very easy), but the corestone gets you a unique water spell (from ability seed).

I attempted to use a Cheat Engine script to set luck to 999 and test, but the way the game handles stats (it recalculates extremely frequently) made changing stats not work 99% of the time. So I edited Strength at the same time and used damage output as the litmus test for whether it was still working or not. I did not notice any difference in drop rates for the couple of battles I had it working for.

Beyond that, I didn't notice any difference in Corestone drop rates from when I was low level vs. later in the game in the 40s, despite Luck going up substantially. It never seemed faster.

I feel comfortable saying that if Luck has any effect at all on Corestone drop rates, it's too minuscule to matter.

I think the game looks at combined luck. I have Morley as in #3 and Bonds of Tomorrow, Luck+, Luck all equipped on the other 2. Also 3rd defeated appears to be the charm for a drop.

I have been unable to get a Shapeshifter core stone to drop. There are 2 places to farm them after they appear: Dorpher - beyond first meridian and Wind Sanctum beyond first meridian and then pass the Marmablues and Kid Drakonis to a party of Kid Drakonis and Pricklebeaks.
