- New styles of playing: Dual wielding, Wands, and Grenades
- Dual wield daggers, wands or other one-handed weapons. This comes with a separate Dual-wielding ability in which you can invest points to improve your proficiency.
- Toss elemental, area of effect, damage-causing, and status-setting grenades. This comes with a separate Bombardier ability in which you can invest points to improve your proficiency.
- Wands are one-handed ranged weapons that deal elemental damage and come pre-charged with an additional powerful skill that the player can invoke 1-4 times depending on his or her Wand skill level. The skill also determines your attack range with wands (from barely-out-of-melee to bow-level).
- New game difficulty modes:
- Explorer mode. Formerly called "Casual," Explorer players will face less-fierce enemies and enjoy a higher chance of knocking them dead, freeing up the player's time to discover, craft, sleuth, and travel outside of combat.
- Classic mode. Formerly called "Normal mode"
- Tactician mode. A totally new game setting featuring smarter, stronger enemies to challenge combat-oriented players.
- Honour mode. Experience Tactician Mode with the added challenge of having but a single save and a single life (no resurrecting!) at your disposal.
- Tactician and Honour modes feature re-designed encounters and puzzles, including new mechanics, monsters, skills, and challenges. Enemy AI is more intelligent and designed to defend against past players' most commonly-used tactics.
- New traps have been added, making perception, tactics/puzzles, and simply moving around in the world a lot more challenging.
- New skills and skill system
- New tiered skill system ('Novice', 'Adept', 'Master') allows you to learn the most devastating skills as you progress in the magic schools of your choosing.

Balancing and Gameplay:
- Skills were rebalanced and redistributed into skill schools to give each a more cohesive theme
- Balancing changes have made mid- and late-game (post-Cyseal) combat more dynamic and engaging
- Existing abilities and talents have been rebalanced
- Weapon ability progression has been updated to further differentiate play styles based on weapon types (e.g. the 'Two-handed weapons' theme now focuses on slow, powerful strikes with a good chance of inflicting monstrous crit, while 'Dual-wielding' is centered around striking multiple hits more and more rapidly as the player levels up the ability.)
- Vendors sell much better loot
- Magical items are built up differently
- Items' use requirements have been revised
- Economy (gold value and rarity of all items) has been revised
- Treasure generation and traders have been overhauled. Item selection by treasure generation is also less random and uses a system that guarantees variation in drops over time
