Earth Cristals farm?

[sesiom000]

Hi guys!
Anyone has an idea of how this item drops and if its actually possible to farm them on a specific way?

Edit:This one 地球結晶

You get 2 guaranteed from clearing XH Tokyo Exploration with an S rank.
The Quick E-Codes (The runaway cars and killing all the enemies around the city in the time limit) will also sometimes give crystals.
Then if you do the featured quests of the day, you can hopefully get a gold key and do the gold bonus quest. That one gives you a lot of crystals in one shot (but it relies on the RNG of you getting a key so I wouldn't rely on that too much).

Cheers

not those i mean this one 地球結晶

Like all the other planetary crystals, everything in Tokyo has a chance to drop them at a low rate. All you can really do is keep running the Tokyo maps to find them.

would using rare boost better my chances of finding those?

Rare drop boost would help to a degree, but you may not realize the effect is there because the drop rate is low to begin with - if Advanced Mission is anything to go by (for every other planetary crystal), they drop even less than the capsules. If you're desperate for the crystals or are swimming in excubes, there's really no reason to not run the booster. Otherwise I'd probably not bother.

ok thanks for the answer!
