Is there a trick on how to get a lot of breachstone?

Yesterday, at around 3am (on my timezone, gmt+8), I buy all esh and tul out of this guy. 60+ esh and 50+ tul. Today(same time), I saw him post a lot of stone again, but using another character, but the same hideout, I remember it because its hard to click the stash, he puts it on the map device. Again, I buy all of his esh and tul stone, 59 tul, 54 esh. After the trade, I asked him how did he get a lot of stone, like I want some tips. And he ignored me.

That makes me think, because he ignores me, i lost 1 of the big seller of stone, is there a trick on how to get breachstones?

Level up Zana so you can buy the Breach modifier when you run maps. Use sextants. Make sure to open any clasped hands and kill all rare mobs when you trigger a breach. Might not hurt if you've got some breach rings with item boost.

Edit - looks like Zana doesn't sell Breach this league. I guess sextants are the only way to boost the number of breaches.

My guess is that person gets breachstones by buying all the cheap ones from other players, then selling them at a profit.

simple tips

1) Run a buttload of maps and hope for breachstones
2) Buy a bunch of puzzle divination cards
3) Buy a bunch of obscure divination cards
4) Buy a bunch of breachstones/splinters

...

5) run breachstones

the answers No OP, other posters are trying to be helpful but there isn't a way to get them quickly, GG sadly put the splinters cards on beyond mobs then made them stupidly rare for only giving 5 splinters, one card only drops from elder portals and again is pretty rare its just a pain in the backside.

Really unfortunate that you can't focus them tbh

There IS a way. There is a divination card that is called The Obscured that rewards you with a breach stone. However, i doubt that it is profitable to buy them off and turn them in. The card usually sells for at least 3 chaos. 7 x 3 so 21 chaos. As long as you are not rewared with a chayula, you will lose money

Edit: Ok @Draegnarrr already mentioned the divination cards. I didn't read carefully enough. And yeah the card seem to be too rare to get such a big stock out of it

That is called flipping. Pretty simple really. Don't know why everyone is trying to find a way to farm 500 breachstones per day, this wasn't farmed.
