From what I understood, Mari"s secret shop can offer better deals but with crystals and in limited amounts. With the last update, there are now T3 Destruction Stones x300, but they cost way more in crystals in the shop than their market value in gold, which is already pretty high.
I noticed some other products like that, for example the fusion materials. Is it normal?
I don’t know the prices right now, but when I was in T1/T2 breath’s and leapstones were far cheaper than on the market, but guadian and destruction stones were either close to the same price between mari’s and the market or slightly cheaper on the market.
Now that gold to crystal has gone up, it’s probably not worth converting gold to crystals to buy from mari’s shop as much as it was 3 weeks ago when I was doing it.
