Raised level cap:
Your party of six adventurers can now progress beyond level 12 to 14. The additional levels add powerful new spells, abilities and talents for all 11 classes.
New areas to explore:
Largely focused on the snowy environments inspired by Icewind Dale, the expansion will feature a new quest hub, and many additional quests and dungeons.
The expansion features mighty artifacts that grow stronger over time. These weapons gain different powers and attributes depending on the character class that binds to it.
Part 1 of the expansion introduces two new companions you will be able to use throughout all of your adventures. The Devil of Caroc, a rogue, and Zahua, a monk, will be available to join you on your quest in The White March and will travel back with you into the base game.
Classes will now have additional options to diversify and take on some of the abilities of other classes.
Party AI: Now you will have the option to set AI scripts for your party, allowing you to focus on controlling the characters you care about most.
Enhanced Enemy AI:
Enemies and monsters are now smarter than ever. The new AI makes the entire game more of a challenge, and spell casters will use a wider variety of their spells in more devastating ways.
At any inn or tavern the player can re-level their party members. It gives flexibility for the player to experiment with the RPG systems and try out builds with the newly added multi-class talents. If you aren't completely satisfied with your character, you can now do a rebuild and start over fresh.
