Ember

early game support

supportsustaindefendertankteam_buffer

Ember is a Heat Defender who keeps her squad alive rather than chasing damage. She stacks Knock Down to apply Vulnerability, which physical-focused teams love, and she converts her own Max HP into party-wide shields while her Combo Skill tops up the active operator's HP. Because her support output is tied to HP and Will instead of ATK, she stays useful without heavy offensive investment.

This is the low-investment version of Ember, aimed at players still progressing through early content. Former Finery is the centerpiece because it is easy to acquire and provides HP, Will and a restoration effect, letting Ember keep the active operator healthy while her Ultimate is still small. The Armored MSGR set supplies Strength — which raises her base HP and therefore her shields — and adds a broad damage-reduction safety net below half health, making her noticeably harder to burst down in story encounters. The Essence priority shifts slightly from the endgame version: Efficacy first to squeeze more value out of the weapon, then HP Boost and Will Boost, since at this stage every point of HP and healing matters more than raw offensive stats. Once you secure Thunderberge and Eternal Xiranite pieces, transition to the endgame build.

Insights

Core Mechanics

Shield generation — Re-ignited Oath slams the ground for Heat damage and hands every teammate a shield scaled off Ember's Max HP, lasting about ten seconds.
Knock Down into Vulnerability — Forward March slams a fan-shaped area to deal Heat damage and Knock Down, enabling Vulnerability for the rest of the team.
Reactive healing — Frontline Support fires automatically when the controlled operator is hit, dealing Physical damage plus Knock Down while restoring that operator's HP based on Will.
Stagger on retaliation — if Ember absorbs damage mid-cast, her Battle Skill slam lands extra Stagger, so eating a hit during the animation is actually rewarded.

Scaling

Strength raises her Max HP, which directly inflates the size of the Ultimate shield — this is the main reason she wants HP-side stats early.
Will is the scaling stat for Frontline Support healing, so it becomes more valuable once you are pushing her sustain role in harder content.
Her defensive kit does not scale off ATK, so offensive stats are largely wasted on her; the second Talent's ATK buff is a low-priority upgrade.
Late game she gains a second layer of value from gear that converts her debuff application into a party damage buff, making her stronger the better her teammates are.

Team Role

Ember occupies the Defender/sustain slot: she is the character you bring when a squad needs to survive rather than race a damage check. Her job is threefold — soak hits, keep the active operator healthy through the automatic Frontline Support trigger, and cover the whole party with Max-HP shields from Re-ignited Oath. On top of that she is a reliable Vulnerability enabler because Forward March applies Knock Down on demand, which physical-damage cores want before their burst windows. She fits best alongside physical carries who already supply their own damage, letting her be the squad's defensive anchor instead of a damage dealer. Because her buffs and shields are team-wide rather than self-only, she scales with the quality of her teammates; in teams that already run the buff-focused gear she adds a redundant layer, so she is most appreciated in compositions that otherwise lack team-wide damage amplification.

Explanation

Former Finery is recommended here because early accounts rarely have Thunderberge, and Former Finery covers the three things Ember wants at low investment: survivability for herself, Will for stronger Combo Skill healing, and a small restoration effect.

Efficacy comes first in the Essence order because it compounds the weapon's own utility, then HP Boost to widen her shield scaling, then Will Boost to improve the healing her Combo Skill provides.

Armored MSGR is the recommended early set because Strength translates into base HP for a Defender, and the sub-50% HP damage reduction gives Ember real staying power in story fights without needing rare drops.

The two Flashlight cores and the jacket/gloves combo are simply the accessible pieces within that set; there is no need to chase mixed pieces before you have access to Eternal Xiranite.

Move to the endgame build once Thunderberge and Eternal Xiranite become available — until then, this setup keeps Ember functional as a budget sustain unit.

Notes

Former Finery is the go-to starter Greatsword: it grants HP, Will and a self-heal, all of which keep the squad alive while Ember is still growing.
It is also the easiest strong option to obtain, since it appears as a choice in the New Horizons banner weapon selector.
The Armored MSGR set leans on Strength for a bigger base HP pool and adds blanket damage reduction once Ember drops under half health.
If you already pulled Thunderberge, ignore the swap and go straight to the endgame plan.
