apart from 1 new mastery, new items and new monsters, below are
some of the other new features as well. 
Personal Stash
Store your extra items in a caravan driver's wagon. If you need
more space in his wagon you'll need to pay a one-time fee. Every
time you expand the amount of space available in the wagon, you'll
pay another fee.
You can also transfer stored items in the caravan driver's wagon
between games. If you place items in the "Transfer Area" of the
wagon, they'll be available for all of your other characters.
Inventory Sort Button
To help you keep your items organized, a couple of sort buttons
have been added to your character screen. One sort button is
present above your main inventory as well as above every extra pack
you manage to acquire.
Lock Item Pickup
As in Titan Quest, you can view all, non-broken, and only magical
loot on the ground using the Z, Alt and X keys. Now when you have
Lock Item Pickup check under the General Options menu, you cannot
pick up a filtered-out item at all, so you'll never accidentally
grab a broken sword again. You will also only be able to pick up
items while pressing a filter key.
Attribute Undo
If you make an error while assigning attribute points, you can now
undo the changes you've made up until such time as you close your
character window.
Additional Quick Slots
During gameplay, you can press B to open up another row of empty
quick slots, which can be filled in just the same way as the
original ten could. You can alternate between quick slot rows at
will, much as you can alternate between weapons with the W
key.
Display HP/Energy
Click on the HP/Energy bars to display your current hit points and
energy as numbers instead of a simple red or blue bar.
New Map Icons
With new map features, there are new map icons. The mini-map is now
much easier to follow, and comes complete with a full legend at the
bottom.
Audio Options
You can not set your audio for headphones or Dolby 4.1 and 5.1
stereo systems. Smashing a skeleton with a mace has never sounded
more crisp.
Difficulty Indicator
We've added an icon on the Character Screen that indicates what
difficulty level you're currently playing on.
Equip With Right-Click
You can now right-click weapons, armor, and jewelry to equip
them.
Clock
If you mouse-over the upper-left-hand corner of the HUD, by your
character's portrait, a real-world clock will appear, to help you
keep track of time.
Adjusted Experience Bar
The experience bar at the bottom of the screen will now glow and
fill slowly as you earn XP, to help you see just how much
experience each slain monster and completed quest is worth.
Gamma Slider
If the lightning in the game isn't dark and gloomy enough for you,
or if it's a little too dark and gloomy, you can set the game's
brightness with the new gamma slider. You can find it under the
video options menu.
Disable Screenshake
If the shaking screen makes you queasy, you can now disable it in
the Video Options menu.
Triple Buffering
When Vertical Sync is enabled, turning this option on can smooth
out framerate. Try it if you are getting some framerate choppiness
from Vertical Sync.
Detail Objects
Enables new small detail enhancements, like footprints and ocean
waves.
Advanced Effects
Enables new graphical enhancements, such as bloom.
