Exchange of Yellow rough-stones

I also made more than a hundred general exchanges with Yellow rough-stones, there was not any HQ Obsidian just like there wasn't any HQ Spodumene at red, however there was a GQ Obsidian, let's see the others:

Exchange of Red rough-stones

Almost a hundred of red rough-stones exchanged with general and didn't get a single GQ or HQ Spodumene... Got these instead:

Exchange of Green rough-stones

Now i used all my collected Green rough-stones with General exchange and get these as a result:

Alchemy - Rate 3

As i promised, i also did some rate 3 alchemies to see, is it worth to pay for the +1 rate to get rate 4, or not? In my oponion it's worth to pay, since i get more materials from the crafting ones, however nowadays they don't have that high value, so you can decide it by yourself going through the table:

The only thing why rate 3 is better than rate 4 is the Sedatives, becaouse you can get them in bulks from rate 3 and you can't get any in rate 4, so if you'd like to stock up with them, rate 3 is better for you.

Alchemy - Rate 4

I also had tons of rate 1 items, so i tried out my luck with the rate 4 alchemy, however i wasn't sure if it's worth to pay for the 1 extra rate, so i'm also made a rate 3 table, you will see it soon, and i got this rewards for rate 4 that are listed in the table:
