EternityBuild and Guide

Introduction

Eternity is a 6✦ rarity character from the Mineral afflatus who deals Reality damage and belongs to the Support class.

In her base form, Eternity is a tanky unit immune to [Bleed], [Corrode], and [Poison]—a good early game carry. Her Euphoria upgrade transforms her into a powerful support for self-damage teams. As her DMG Taken Reduction, Crit Rate, and Crit DMG buffs scale with Lost HP, Eternity forms a solid support core with Semmelweis.

Tier I

After attacking, consume (their own Max HP x10%) HP from all allies to deal an additional (the team's combined Max HP x7%) Genesis DMG to the target; if an ally's HP is already below 50%, that ally does not lose HP this way.

Tier II

When entering battle, grant (Eternity's Max HP x5%) Max HP to other allies.

At the start of the round, for every 10% missing Max HP on an ally, grant DMG Taken -5% to that ally, stacking up to 25%.

Tier IV

When an ally attacks, for every 10% Missing Max HP the ally has, the ally gains Critical Rate +4% and Critical DMG +6% (stacks up to 5 times); if the ally's HP is below 50%, then the ally's excess Critical Rate is converted to Critical DMG.

Review

Eternity functions as a hard-to-kill DPS character, offering remarkable sustainability through her Insight passives, Blood of Longevity/Immortal, and her Ultimate. These skills synergize to provide her with substantial self-healing while dealing significant damage.

Since she unlocks Blood of Longevity at Insight 1, which not only provides the benefits mentioned earlier but also grants complete immunity to Bleed, Corrode, and Poison, she's a character you'll want to invest in early on. Her Ultimate ability gives her significant solo potential, as with no team members, she can use her ultimate more often, providing excellent sustainability.

In a team setting, one healer is needed to effectively maintain her HP at a reasonable level.

Pros & Cons

Pros

Complete immunity to [Bleed], [Corrode] and [Poison] is niche, but excellent when it needs to be.
Great self-sustain due to [Blood of Longevity / Immortality] and the Leech Rate provided on the Ultimate.
Euphoria: Completely reinvents her kit, switching her to being an amazing HP Loss Support that grants a consistent way of dropping allied HP while applying various defensive buffs like +HP and +DMG Reduction. On top of that, she grants +Crit Rate and DMG (and Crit Conversion) ramping with lost HP.

Cons

Low personal DMG output when compared to most Damage Dealers and even some Supports.
“Tanky” Damage Dealers are not a well-supported niche due to the existence of units like Kakania, you’d rather have DMG instead.

Resonance Builds

Build 1 - Eternity – Euphoria Max HP/Crit

Level

R10 - Genuinity (Incantation Might/DMG Bonus)

Code

AvAkNBU0VTlDKgQ8ADwQO1IrQCQhJiBAQUpS

A mix of Critical Rate, Critical DMG, and Max HP. For a more support-oriented Eternity build. Eternity’s Euphoria buff allows her to increase all her allies’ Max HP by a percentage of her own Max HP at the start of battle. She also deals additional Genesis DMG that scales off of all allies’ Max HP after attacking. At ≤50% HP, excess Crit Rate gets converted to Crit DMG so this build also includes some crit.

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

Level

R10 - Genuinity (Incantation Might/DMG Bonus)

Code

Prioritizes Critical Rate and Critical DMG. For a more damage-oriented Eternity build. Stacks as many Crit Rate and Crit DMG pieces as possible but has less Max HP.

Psychubes

From The Depths

In the Shadow

Hopscotch

The Fighter's Best Wishes

Beyond Wonderland

Comments

For Main DPS Eternity, “Hopscotch” and “Night After Night” are your best bets. Both psychubes increase both Incantation and Ultimate Might. “Night After NIght” also synergizes perfectly with Eternity's [Blood of Immortality] while providing a little DMG bonus at below 80% HP.

For Euphoria Support Eternity, “From the Depths” is a pretty good option. However, as you'll likely be running her with Semmelweis, decide which of the two you'd like to protect more with the revive from “From the Depths”.

As Euphoria Eternity increases all allies' Max HP by 5% of her own HP, the HP% substat on “The Fighter's Best Wishes” and “Beyond Wonderland” make them good options for a support build. “The Fighter's Best Wishes” makes Eternity tankier with its DMG Taken Reduction passive. “Beyond Wonderland” increases the HP Eternity gets back from her Ultimate if she uses her [Nasty Wound] debuff. Since she is also a Crit support with excess Crit Rate conversion, the 21% Crit Rate from “Beyond Wonderland” is also a great addition.
