Gotcha. I must have read the Wiki wrong! As for online, I'm playing with the girl on 3DS' so it may be a bit of a challenge. We're currently working through the HR2 stuff that's why I kind of have to gear up in Offline as much as I can. She's going at her own pace and has about 3* offline level stuff I think with some higher rank stuff here and there. I just got addicted and almost at the 100 hour mark since launch, lol. I said "dang, haven't been this hooked in a game since WoW" and she just looked at me and said "yeah ... ". BUT, she's pretty addicted to, ha! She has almost 60+ hours and she got the game a week after me!
From my understanding, it's a randomized table that is assigned to your saved game. Some are really good, some are shitty (according to users). There were ways to find out if you were on a specific table, if you download the Ping application (
here) there is a Rnd Table (T) button that you can fill in random charms to see what table you have as some charms are available to certain tables while others are not.
I remember there were steps to make sure you had a good table at the beginning requiring fishing and reporting what came back, not sure if that website is up still or not.
Here's a good thread
I'm not even sure if it's something that 'matters' but being a min/maxer from my MMO days I read that thread to find out how to get no T10 which seems to be great all around. Both the girl and I did what is explained in that thread.
From what I've read, 12 + 16 are the ones you can't get Rustshards (whatever they are used for, end game stuff I think).
So with that application, I look at my Charms in-game:
And then input them into the table, I can see I am not on T12, T15, T16, or T17 because that combination of charms isn't on those. (most likely I'm T10 as that's the one I was going for with the directions in that link, plus I've gotten a Rustshard mining in the volcano)
