From the release notes:
Randomly generated treasure has been improved to better scale to player power at all levels of play.
The following only applies to new items that can be found throughout Ebberon and the Realms:
There are many new item effects and higher bonuses to find!
Notable new effects to find include Improved Vorpal, Energy Absorption, and Doubleshot, +10% Dodge, among many others.
Some effects have been rebalanced or removed, with the overall goal of reducing the proportion of items which are of very low quality for their level.
New randomly-generated items will no longer be able to appear with Race Restrictions.
Instead, new items have a chance to appear with “Masterful Craftsmanship”. An item with Masterful Craftsmanship has a lower minimum level to equip than an item with its enchantments otherwise would.
So what's new and exciting?
So far:
Speed VII - Passive: +30% Enhancement Bonus to Movement Speed, +7% Enhancement Bonus to Melee and Ranged Attack Speed. A take on "perma-haste" it seems. Found it on gloves with Strength +8 - Ogre Power +8 Gloves of Speed (no mention of the level of speed in the name, more AH searching limits), +15 min lvl 24.
Also found Clever +7 Necklace of Bluffing +17 as +15 min lvl 24, which seems lower than it would have been before?
