1. I see you can have the magic glyphs of different levels. You buy them from the shop (level 10 out of 50).
When the new 0.3.015 version of PS Clients came out, a new feature was that items, especially weapons would degrade through use and would need to be repaired before they broke. This has been implemented by activating the Quality Attribute of a weapon. The default value seems to be 10.0/50. This default value for Quality has been applied to ALL items that you can store in your Inventory, and not just to those items that can be equipped.
In my character's Inventory I have two items that have Quality: 10.0/50 -where can I get a Falka repaired to 50/50, and where do I go to get Rinna's Note repaired to 50/50?
It isn't the Items that you improve, it is your characters Skills and Stats that you Train up to improve your ability to use them, and use them so you can get more Training... this applies to Weapons and it also applies to Magic.
