That didn't work, I used like 10 of them. I guess I'll just wait until next playthrough. It said before Zaude... but that's a weird way to put an arte. Must be a new hidden thing to piss people off... LOL
Kouli's sidequest guide doesn't even make mention of that arte until after Flynn joins you in Aurnion. I've only found one inaccuracy in his guide at all (I guess you can get the Dark Enforcer title before you go back to Zopheir to create Undine) and I used it for the whole game. Kouli's guide just says to repeatedly use any tent item on the world map to learn it, so I doubt you've missed it.
That said, though, I used Aselia at the same time, and it mentioned being able to get it as early as Zaude, so I did.

I guess this one is wrong then. I guess a lot of different numbers and arte ordering made this seem like I don't have it, but I swear to god, I did see the event before. I have finished the Dog Map Quest, so I practically have used over 30 tent type items.
I'm using the Menu Patch, and the only arte that's not mentioned is called Shining Field. I look at this chart, but I don't see it. However, TP consumption in the game is 25 and the one on the wiki is 26. Small typo and all, so I thought it was some other arte....
So the only thing left is someone to confirm that Kouha Senshoujin (Shining Field) in there game is really 25 TP and not 26, which is listed on the website. Apologies if I caused anything negative.
