Wrath of the Lich King (and also the upcoming patch 3.0) includes a new tradeskill: Inscription. Inscriptionists will be able to create scrolls, off-hand items, and parchments to help enchanters sell their wares. However, their key crafted item comes in the form of spell/skill enhancing Glyphs.
Some of the various Glyphs enhance existing abilities, while others add utility to skills that change its function completely. The current Rogue Glyphs come in 3 major flavors: cooldown/energy cost reduction, range increase, and damage/effect increase. After the cut, let's explore these groups individually.
