apart from 1 new mastery, new items and new monsters, below are some of the other new features as well.
Personal StashStore 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 ButtonTo 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 PickupAs 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 UndoIf 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 SlotsDuring 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/EnergyClick 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 IconsWith 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 OptionsYou 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 IndicatorWe've added an icon on the Character Screen that indicates what difficulty level you're currently playing on.
Equip With Right-ClickYou can now right-click weapons, armor, and jewelry to equip them.
ClockIf 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 BarThe 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 SliderIf 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 ScreenshakeIf the shaking screen makes you queasy, you can now disable it in the Video Options menu.
Triple BufferingWhen 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 ObjectsEnables new small detail enhancements, like footprints and ocean waves.
Advanced EffectsEnables new graphical enhancements, such as bloom.
