Sunday is a Support character with an absolutely stacked kit for boosting your DPS carry's damage output in Honkai: Star Rail. He has some of the best parts of other popular Harmony characters, as well as a special effect that gives him his own niche in the game's ever-growing roster.

Faith Outstrips Frailty is one of the best Eidolons for Sunday in Honkai Star Rail. If he has this power-up activated with a complete build, clearing end-game activities like Pure Fiction, MoC, and Apocalyptic Shadow becomes quite easy.

A staple amongst all the Harmony 3-star Light Cones, Chorus is a great option for players who are new to Honkai: Star Rail. Since new players might have difficulty obtaining other 4-stars, starting off with this can be a safe enough option.
