Tears of Veeshan offers new Tradeskill quests, tradeskill collections, recipes, new tradeskill apprentice recipes, purple war runes you can craft, and Gemstones which can upgrade Advanced Solo and Heroic gear as well as many other new features. There’s also a great change to building blocks and a new pack pegasus.
From Niami Denmother of EQ2Traders:
There is quite a bit going on regarding crafting in the Tears of Veeshan expansion, and since one of the SOE Dev team, Caith, went to the trouble of putting together a master list for us for beta, I am taking that list and running with it.
