Please answer these questions:

-What, when do I meet, where, and who are the Superiors, Elites, and Bosses?

-Whats the Arena?

-How do I pronounce all the names of the Sylesti species?

-What is the Leave Comment button?

Sorry, Im rather new.

-What, when do I meet, where, and who are the Superiors, Elites, and Bosses?

These are just denotations for the number of stars something has, superior 3, elite 4, boss 5


-Whats the Arena?

Located in Ethernia in Astryl's Vale. You can fight in the arena, unlocking more as you win.
There's 5 challengers in the lv25 bracket (and an 'endless mode' 6th which is not mandatory to unlock more) and 5 in the lv50 bracket (plus another endless mode)
you need to beat each of the challengers to unlock the next, with the 5th lv25 bracket unlocking the lv50 bracket.
Only pets of or under the bracket level can fight in the battles (eg, lv24 can do lv25 bracket, lv26 cannot)
The purpose is pretty much just to get arena marks. These can be used to buy Tamed ny'vene hatchlings from the ny'vene shop, or assorted items, namely avatar items or pet equipment, from the arena shop (not... much point to buying the gear though? The lv25 gear isn't as good as lv26 saerielle gear for lv30 battleboard teams, and the lv50 gear isn't as good as lv50 mythic gear from DotF)


-How do I pronounce all the names of the Sylesti species?

You'd have to ask Krinadon


-What is the Leave Comment button?

Not sure what you mean by this? Can we get clarification on where you saw it for the context?

The Leave Comment button is on everyones except your own profile. For example: For me, I see it on your profile, but not on mine. For you, you see it on mine but not on yours. Also, its always greyed out.

Hi Krinadon,
I was just wondering how to pronounce the names of all the Sylesti species. Could you tell me the pronunciations?
Thank you.

probably a feature that was either disabled or never fully implemented, but which might be once user pages are overhauled in the future.
Possibly Krin tried it but it caused some kind of issue like slowdown or something, so he put it on hold (would have been back when the site was a little baby, back before I ever even got here. I'm guessing it might be that since I think that's along the lines of why the trophies you see on the pages of very old players were disabled?)

Probably

Unfortunately the sounds files no longer are available, but here is the thread going over pronouncing the species.
