Alchemy - Rate 1

I tried if it's worth the trouble to do rate 1 alchemy, but as i found it, it's not, let's see the rewards list:

Alchemy - Rate 2

I tried alchemy at rate 2, it's also not really worth to do better if we put another rate 1 item in to get rate 3. Let's the table about rewards:

Alchemy - Rate 5

I tried out my luck, but Rate 5 also seems like a not worth to do alchemy rate, so i made only 100 trades, let's see the reward list and rate in the table:

Alchemy - Rate 6

I tried out alchemy Rate 6 and in my oponion it's worth to pay a little more for rate 7, so i made only 100 tries with rate 6 to make an acceptable table about the drops, so let's see it:

Alchemy - Rate 7

Since i collected up many rate 2 items, i tried my luck with them by giving a +1 rate with vis. I got many different items as rewards, i'm also get a few Piece of Narakas from 5 types and 6 pieces in total. You can chek all my rewards from the attached table:
