Well! this Steem Monsters Puzzle #2 might have been difficult to solve but it was far from impossible!
Here was the path that led you to the solution:
Statement was:
“Cerberus needs to know who he really is. Will you help him?”
Like the first puzzle, the image name was a hint to help you to solve this enigma.
Checking the source code page you would have seen the picture name was:
This telling you that the solution to this puzzle was Cerberus card id
The first step was to extract the text hidden in the picture.
You could have used this tool or Stegsolve to find it:
XU U9 W3 W3 ZV WY WW VZ UU ZX XS V4
That time I did not used a Caesar Code but a Vigenere Code with Alphabet + Numbers
“ABCDEFGHIJKLMNOPQRSTUVWXYZ123456789”
The key you needed to decrypt the string above was
42362 (numbers in picture).
You could have used Dcode tool to decode it:
43 2D 49 5A 43 37 41 36 32 45 41 38
Then you would have found out this Hexadecimal string.
Using that tool
you would have seen that the ASCII conversion was:
C-IZC7A62EA8
Solution: Cerberus id is C-IZC7A62EA8
I am aware that this one was a bit more complex than the first one but it is showing you different websites and tools that I might use for my puzzles. So good for you to know them ;-)

Thank you all for your participations!
I can already tell you that the next one will be easier than this one and that you will just need a little knowledge in decoding (with tools/codes used in #1 & #2).
Most of the time, you will have to use your logical and treasure hunt skills.
