v.146 - Return to Masteria Update Notes

Pretty much it's something like this:

In the past:
you got a code from one of the ITCG cards (you get an ITCG material from it).

Then if the material is a base material, you start a "quest Chain" (Different NPCs where involved in different items) that leads you to forge an item.

now:
So, right now It'd be something similar but you get the materials from a NPC.

Basically, you got items for redeeming codes off of physical trading cards.
A number of different NPC in Masteria required those items to craft special equip (or as payment to give you recipes needed to craft).
Other items, like the upgraded Stirgeman stuff or Taru weapons needed a base piece of equip from itcg, and some in game drops to attempt an upgrade.

Ah right, thank you both.
I remember getting a El Nathian Cape in the past and not knowing what to do with it, haha.
