Just want to check before i go to the trouble of getting an artisan seal to attempt the combo, but are all of the Artisan Seal + 1 item trophies in game during Velious era? I know poison making is for sure as is brewing but wanted to confirm that the others are, specifically alchemy using the potion of mystical aptitude.
Yup they're in. Keep in mind you can't make the 100% WR bag they summon permanent until Luclin since the turn in guy is in the bazaar.
