37Build and Guide

Introduction

37 is a 6✦ rarity character from the Star afflatus who deals Mental damage and belongs to the Sub DPS class.

A sub-DPS who synergizes well with many characters, 37 is also able to serve as a main DPS at higher Portrays.

37 is a strong supportive damage dealer who gains Eureka to cast [Supplementary Formula], a mass attack that deals 120% Mental DMG and 40% Genesis DMG. 37 gains Eureka when she casts her incantations and when her allies cast follow-up attacks (FUA). As a result, she scales well with teammates who cast frequent FUAs.

Her Insight III increases the Critical Rate by 20% and allows her Genesis DMG to score critical hits. You'll want to unlock this early to capitalize on 37's naturally high Critical Rate and unlock her synergy with other crit-based characters.

On top of granting herself Eureka, her incantations deal Genesis DMG that scales directly with her ATK. [Triangulation] is a single-target attack, while [Curve Mapping] is a mass attack that also grants her a stack of [Sturdiness]. The [Sturdiness] helps to balance out 37's notorious squishiness.

37's ultimate [Kingdom of Geometry] grants herself +2 Eureka and 2 stacks of [Enlightenment], a single-use Genesis DMG Dealt +100% buff, while her allies get 2 stacks of [Numeral Perception], a single-use ATK +10% buff. [Kingdom of Geometry] grants more Eureka at Portrays 3 and 5, allowing 37 to cast [Supplementary Formula] more often and serve as a competent main DPS.

Pros & Cons

Pros

Synergizes well with a wide variety of FUA characters
Outputs a considerable amount of Genesis DMG, which is only resisted by a few enemies
Works well as a sub-carry and even a main damage dealer at high Portrays
Can become an AP-positive AFK [Supplementary Formula] bot on teams with frequent enough FUAs

Cons

Mediocre damage output at P0, realistically needs P3+ to be considered a competitive damage dealer
Her ultimate is a notoriously bad support tool (the buffs matter very little—it's just for Eureka)
Provides little to her teammates besides FUA damage
Extremely squishy; 37 has a lower HP stat than some low-rarity characters like Sputnik and Rabies

Overall

Resonance Builds

Build 1 - 37 – Full Crit (P0)

Level

R10 - Aspirational (Critical DMG/ATK)

Code

BClFJiQtFCQEQVJBUDlAKAEqAEMyRzA8IEpl9EM

Prioritizes Crit Rate and Crit DMG as much as possible. Ideal for teams with Flutterpage, who provides DMG Dealt and Genesis DMG Dealt through her Forcefield. Use this build with On the Hand of Time (Flutterpage’s signature psychube) for even more Crit DMG; Flutterpage can use Same Old Story or Knock on the Door instead.

If you don’t have Resonance Patterns unlocked, try this build with Placidity:

AClFJiQtFCQEQVJBUDlAKAEqAEMyRzA8IEpl9EM

Build 2 - 37 – Full Crit (P1+)

Level

R10 - Aspirational (Critical DMG/ATK)

Code

BPQkJQAsASpQKFE4BThFK0QlBEQDRSI0MDQy

Slightly higher Critical DMG and ATK but lower Crit Rate compared to the P0 Full Crit build, since P1 gives 37 a free 40% Crit Rate boost when entering battle.

Build 3 - 37 – Max Investment Crit

Level

R12+ - Aspirational (Critical DMG/ATK)

Code

BDhFOAUoUUBQQEIrRCsAJQQkAS0RRTBFQEUy9CQ

At R12 and above, 37 gets access to another Crit DMG piece to boost her damage even further. Best used with Flutterpage.

Build 4 - 37 – Balanced

Level

R10 - Placidity

Code

ACdFKQU6BDpEPAA8EEAgQjAnIkQiKlAoUfQk

1000 more HP and slightly higher ATK than Full Crit, but with less Crit Rate and Crit DMG. A generalist build for those who struggle to survive, but outputs lower damage.

Psychubes

On the Hand of Time

Falling for a Sweet Phenomenon

Silent and Adoring

Long Night Talk

Knock on the Door

Comments

On the Hand of Time is great for 37 comps with very frequent FUAs, and works well in teams with Flutterpage. At max level, 37 can stack up to 60% Critical DMG. Make sure 37 can cast her FUA twice in a turn to get the full effect.

Falling for a Sweet Phenomenon is 37's Anecdote psychube and works well for any non-AFK 37. Use this if someone else is using On the Hand of Time.

For pure AFK-bot 37, use Silent and Adoring instead.

Long Night Talk is best for people running P5 DPS 37, as her ultimate can proc its passive.

Knock on the Door increases her Critical Rate and FUA damage. Use her with a [Burn] applicator like J to get the full effect.
