How long after an item gets released is the wiz ard supposed to ask for them? I thought it was a week but he just asked me of a Blue Gladiator Sandal which only came out less than 3 hours ago

The wizard asks for anything and everything

I've had multiple asks from all the NPC quests of items that are not even in shops

I know he asks for anything but i thought there was a time delay between an item being released and it being asked for in quests. But i guess i may have been wrong about this :P

As far as I'm concerned, there isn't a time limit for how soon he can ask for them.

Absolutely no time delay for questgivers. It can pop up in a quest as soon as the item is in the database(even if it hasn't been on the news or stocked in a shop yet) :P

The wizard doesn't 'know' that it's new. That would nvolve Subeta staff having to manually updating the items to 'not so new any more' after a few weeks. Seems a bit silly :P
