ROUND 1
First, we should...
ROT13 the whole thing.

Simplified for human eyes, the instructions are as follows:
Yes, good. You are intelligent. You have unlocked Round Two. Now use this text as a key to the following Vigenere cipher:
ROUND 2
Following these instructions, we execute Round Two.
Use the entire original string to key in a Vigenere cipher of the entire block of (already ROT13'ed) text that follows it.
After this step, the remaining message now reads:
Round 2

As you can see, the instructions have been garbled. That's because they're obscuring...
The word VIGENERE
ROUND 3
So let's go ahead and try to follow our instructions with a little guesswork.
We can already assume that the leading text is "Round", so let's let a Vigenere solver do the heavy lifting and reverse-solve for a key. It came up with variations on THIRT?
. Remember our instructions were cut off at "the 13's..." so let's try THIRTEEN
as a key.
With that done, here's the result:

So... that was kind of right and kind of wrong, then?
ROUND 3, TAKE 2
Let's keep going...
Do it again! Run a Vigenere with THIRTEEN
as the key.
Our message now reads...

Round 3, still going
So our new instructions are...
If we include the oddly-capitalized characters in the intro text, XOR EACH CHAR AND MINUS 1
Getting closer! Now to prepare for the next decryption...
Because XOR is a binary-based operation, we need to translate the message into binary. Now, since straight-up translators don't play nice with that special (Unicode) character in there, I've used an automatic encoder but lightly modified it by hand.

So we run the instructions with a ... modified message.
Remember "MINUS 1"? Well, according to OP, this was actually what was done to ENcode the message, so to reverse the process, we're going to take each! and! every! character's binary and increase it by one...

...and then XOR the sucker with 00001101
(thirteen in binary).
EUREKA! That was a chore.
#round 3
Very good, very very good. Impressive. Great as it is, there's more. Everything you've done so far is great. Nobody has gotten this far. Everybody just gave up at round 2... Round 2 was too hard wasn't it? Kind of, but like... Everyone gave up... You haven't, sooo get ready for round 4 i guess.
