The most recommended thing to add to the sword dance poet in Baldur's Gate 3 is to increase the charm, so that you can choose different spells according to the poet's main combat power to fight.
Answer: The most recommended addition for sword dance poets is charm.
During the battle, spells are still cast according to the player's main battle, and corresponding equipment can be obtained in conjunction with the first chapter.
Recommended attribute points: 8 strength, 16 agility (+1), 14 body, 8 intelligence, 10 sense, 17 charm (+2).
The Sword Dancer is usually selected at level three. After making the selection, you can choose different spells to attack.
