These magical items are created through the process of
Glyphing. When used, a glyph will apply the stats listed on the item to your stats for the duration displayed. When the time expires, the stat bonuses will disappear from your character. Additionally, if you log out of your character for any reason, any glyphs still active will turn off.
Same stats from a Glyph cannot stack, however, you can use multiple Glyphs containing multiple various stats.
