I know "A Porcine of Interest" is a new quest and all, and they wanna promote it (hints in the medium task). But of all the things to be region locked in Asgarnia, I dont think the slayer helmet should be one of them. The quest should work as other similar introduction quests. An example would be Eagle's peak, you unlock the ability to use the box traps after the quest is done, but box traps as they are can be purchased in hunter shops prior to the quests completion. Goggles should work the same way, or should not be a necessity for crafting a slayer helmet. (This post is mainly me justifying not picking Asgarnia, because i wanted to pursue the mage relic, but that doesn't mean I think my reasoning is wrong
) Thanks for taking the time to read my thread!
Kandarin + Asgarnia trumps everything else
Are you sure? As I interpreted the info on the wiki, the slayer helmet doesn't require the goggles until after the quest is completed. I'll probably find out first-hand fairly soon, anyway...
I remembered that I haven't completed "A Porcine of Interest" on the main game. So just now I dismantled my slayer helmet and put it back together, with no sign of any goggles. It seems there's no problem!
