A few Questions
 

1. Is cultural tailoring/smithing ingame? i wasnt sure if that was all related to a future expansion or if it was included in original eq.

2.(maybe a comment) I don't remember when it was But pelts did become stackable in live for the better of the game In my opinion. (feel free to disagree) every other trade skill's ingredients are stackable for the most part.

3. i thought i had another but couldnt think of it when i got here. maybe later..

Pelts were always non stackable in classic as I remember. And cultural tailoring/smithing I don't believe is in game. I didn't tailor/smith at all in classic so I don't remember specifically.

pelts were not stackable in classic and I think cultural tailoring and such came in during velious IIRC.

ok that works thanks for the reality check.. I am curious however about something,

Can mages summon the focus items they eventually got?

Nope. Not classic. Can't remember when they went in, but I don't think it was Kunark or Velious.

I believe focus items came during Luclin, or PoP

Luclin
