The Celestial Warlock Subclass mod for Baldur's Gate 3 introduces a well-crafted adaptation of the Warlock class from Dungeons & Dragons 5e, specifically from Xanathar's Guide to Everything. This mod allows players to experience the Celestial subclass from levels 1 to 12, providing full support, compatibility with multiclassing, and a balanced gameplay experience that respects the original game's mechanics. Players can also enjoy partial support for levels 13 to 20, catering to those who prefer extended gameplay without level restrictions.

Key features include unique abilities such as Healing Light, which utilizes Celestial Energy Points for healing, and an expanded spell list that enhances the Warlock's capabilities. New invocations and options, like Bearer of the True Flame and Sacred Living Flame, offer strategic alternatives to traditional gameplay. The mod's design ensures compatibility with other mods using the merge system, enhancing the overall experience without overriding existing game content.
