Sword Dancers are the order of specialized clerics of Eilistraee that focuses on directly emulating their goddess; becoming artists, diplomats, leaders, and protectors of the followers of the Dark Dancer. They are an extension of the goddess’ own motherhood of the drow people; aim to assist and protect other Drows that need help, especially from the grasps of Lolth. They also often take the role of emissaries among other races, promoting the harmony and cooperation between Drows and other races.

Note: I do not want to make a cleric clone and thus can not prevent you from playing a Lolth Sword Dancer.

Class Detail

Some of the features are changed when adapting to BG3, notably:

Domain spells (because some spells dont exist in bg3 and im too lazy to make them)

1: Magic Missile, Charm Person
2: Moonbeam, Extract Poison
3: Lesser Spellsong, Beacon of Hope
4: Freedom of Movement, Soothing Spring
5: Spellsong, Blink Charge

Moonfire Flare: both healing and damage are triggered at the same time to prevent the annoying interrupt popup on every attack.

Lesser Spellsong / Spellsong: removing concentration is too annoying, so instead you may cast a 3rd/5th level spell or lower without using an action.

Evensong - Regenerate: regenerate is not in the game, so i used my 2e spells version of regenerate

Grand Chorus: no teleportation, just use way points

Eternal Dance: removed the reaction to dodge OA feature
