Avowed's anniversary update introduces new features including stat bonuses, customizable difficulty modifiers, a New Game Plus mode, and a new staff weapon type. It adds three new playable races, expanding options beyond the previous choices of humans and elves. The update faced challenges in ensuring character customization worked seamlessly across the new races, but lacks unique dialogue choices for each race due to the writing team's focus on other aspects. Each new race provides different gameplay attribute bonuses, enhancing the gameplay experience. The update is available at no additional cost.
