Some Magicka DLCs Giveaways [Solutions posted!]

Hi there!

So I had some money left on my Steam account and that was enough to buy some Magicka DLCs on the recent sale. :D

Magicka: Grimnir's Laboratory
Magicka: Nippon
Magicka: Wizard's Survival Kit (Hint!)

No CV required for any of those. All of them are single-step puzzles.

I'll post solutions when they'll end.
Good luck! ;)

UPD: Solutions

First one you just need to rotate to the right by 90 degrees and flip it vertically (or other rotate operations that give the same result) and then you'll get a valid QR code, which can be easily decoded here.

In second puzzle you had to translate "o i i z e s" with 1337-alphabet, that will give you "0 1 1 2 3 5". As you may guess, this is Fibonacci sequence, and after 2178309 in it goes 3524578.

The last puzzle was pretty easy as for me, but it turned out to be the most difficult for you. It was encoded with Ascii85 (or Base85). Just because Base64 is too mainstream. :D

And the hint. It was very easy, you just had to find my Lucid giveaway and check its description for a hidden link. The hint was "85", that was very helpful for solving third puzzle.

Thanks for entering my puzzle giveaways and congratulations to the winners!
