Now that the most anticipated character from Penacony is finally playable and everyone hopefully had lots of luck pulling him, here’s a full guide on how to level and build our dear Sunday. So let’s dive right into it!

Sunday farming guide

Sunday is an Imaginary type character following the Path of Harmony. So if you haven’t pulled him already, what are you waiting for? (And what are you even here for?)

Ascension Materials

To start off, let’s focus on leveling and ascending Sunday to level 80. For this, you will need, in total:

MaterialAmount needed

While Sunday’s banner is up, you will get early access to the Stagnant Shadow that drops Chordal Mirage. Otherwise, you can locate it in Penacony’s Grand Theater.

Now that we’ve levelled everything that isn’t RNG based, it’s time to suffer. All for his sake, of course! We all want our boy to be the strongest he could ever be.

Lightcones

Lightcones are likely the easiest part of building a character, and that’s no exception here. Here are all of the Lightcones that work best for him.

Relics

Eidolons

To close this guide out, let’s talk about Sunday’s Eidolons and rank them best to worst — though none of them are terrible, some are just that broken. Whether for the extremely committed fans or the whales, we hope this is useful for you in one way or another!

EidolonDescription
E6The Talent's CRIT Rate boost effect becomes stackable up to 3 time(s), and the Talent's duration increases by 1 turn(s). When Sunday uses Ultimate, can also apply the Talent's CRIT Rate boost effect to the target. When the Talent's CRIT Rate boost takes effect and the target's CRIT Rate exceeds 100%, every 1% of excess CRIT Rate increases CRIT DMG by 2%.
E1When Sunday uses Skill, the target character can ignore 16% of enenmy target's DEF to deal DMG and their summon can ignore 40% of enemy target's DEF to deal DMG, lasting for 2 turn(s).
E2After the first use of Ultimate, recovers 2 Skill Point(s). The DMG dealt by "The Beatified" increases by 30%.
E4When the turn starts, regenerates 8 Energy.
