Etheria Restart Best Supports and Healers: Shields, Buffs, and Sustain Units To Prioritise​

Support and sustain units are what let Etheria Restart accounts punch above their raw stats, especially in Threshold, Aurora, and PvP. Lingluo, Freya, Lily, Beyontin, Veronika, Celince, Helkid, Gray, and a handful of SRs like Valerian sit at the top of 2025 support/healer rankings and are worth prioritising even over some DPS.​​

S+/SS tier supports and healers to build first

Multiple tier lists and guides agree there is a small group of “never‑regret” support/sustain units.​

• Lingluo – premier healer/sustain
  • Called “the best healer in Etheria Restart” with “ridiculous healing output” that can “cheese stages with raw sustain” in long boss fights.​
  • Brings strong heals, regeneration, and debuff dispels; Pocket Gamer notes that her kit is “about buffs, debuffs, or enhancing existing buffs,” making her slot into almost any team.​
  • Free after seven days of play and rated SS/SSS in several lists, so she is the safest sustain investment for PvE and PvP.​
• Freya – hybrid support / off‑tank
  • LDShop describes Freya as striking “a perfect balance between aggressive pressure and team support,” with Dreamweave giving teamwide cleanse and Nightmare debuffing enemies.​
  • Enjoygm’s tier list puts Freya in SS with a note that “Freya’s heals trivialize sustain checks,” and ZeusX’s November list highlights her mitigation and counter damage as a top front‑liner.​
• Lily – top pure support
  • A HellHades article explicitly calls Lily “arguably the best support in the game,” praising her speed buff, damage amplification, and cooldown manipulation that “benefits every DPS.”​
  • Recommended as a reroll priority who will “likely never be powercrept” due to universal compatibility with most carries.​
• Beyontin – revive + damage amp
  • Enjoygm lists Beyontin as S‑tier support and Escapist’s guide stresses that she “can revive your team, period” while also buffing ATK and Crit DMG, making her SSS for hard content like Aurora and Terrormaton.​
  • HellHades’ synergy guide treats her as a utility support focused on revive and rotations, pairing well with fragile hyper‑carries.​
• Veronika – buff‑steal and control
  • Enjoygm and HellHades both emphasise Veronika’s multi‑hit control and buff stealing; she is described as an “absolute menace” that locks down enemies while shielding allies.​
  • Frequently rated SS in multi‑mode tier lists because she offers both protection and disruption.​
• Celince – debuffer / mitigation
  • HellHades groups Celince among the best debuffers, praising her for stripping buffs and applying damage‑reduction/DEF break effects that make bosses manageable.​
  • Enjoygm places her alongside Lingluo and Freya in SS, noting that “Celince’s debuffs reduce incoming damage and make nukes land harder.”​
• Helkid – sustain + off‑DPS
  • Escapist’s healer list ranks Helkid SSS, calling him “an amazing off‑DPS unit with great survivability,” whose Shroud Barrier buff is key to boosting his kit while also offering stun and ATK debuffs.​
  • Enjoygm similarly lists Helkid in SS with Lingluo and Freya as endgame clearers.​

Other high‑value supports and healers

Beyond the absolute meta top, several supports are consistently recommended for general accounts, especially as easier pulls.​

• Gray – early/mid‑game buffer
  • Identified by HellHades as one of the best early buffer/support units, providing Crit Rate, ATK/DEF buffs, and AoE DEF‑ while cycling turns quickly.​
  • LDCloud lists Gray as a top SR support because he massively amplifies DPS output and stays useful well into mid‑game.​
• Sania, Mia, Valerian – alternative sustain
  • Escapist rates Sania S‑tier sustain for her combination of heals, purify, and optional revive, calling her “extremely flexible” for most content.​
  • Mia is described as having “a bunch of heals and shields” plus a strong cleanse, making her solid everywhere except niche bosses like Aurora.​
  • HellHades’ “Best SSRs & SRs” article highlights Valerian for shields, heal‑over‑time, and invincibility, calling her a great support when you don’t run Tiamat.​
• Chiaki (both base and Echo) – heal/rotation hybrid
  • HellHades notes that Chiaki can heal and reduce damage, functioning as a pseudo‑healer with rotation support.​
  • Enjoygm puts Chiaki the Echo in SS, describing her as able to “adapt to any wave” and amplifying team damage via tempo.​
• SR standouts: Valerian, Cachi the Guard, Fangus
  • A Reddit thread on best SR heroes lists Valerian and Cachi the Guard as “the best SR support units,” with strong shielding, utility, and general survivability contributions.​
  • Fangus is called the best SR DoT unit, pairing well with curse‑based comps for sustained damage and indirect team protection.​

What these units actually do for your teams

Support and sustain roles break down into distinct categories that guides use when recommending teams.​

• Healers and sustain
  • Lingluo, Helkid, Freya, Sania, Mia, Valerian, Dorothy (base), and Chiaki provide heals, HoTs, shields, or damage reduction.​
  • Lingluo and Freya are singled out as being able to carry sustain checks by themselves in long boss fights, while Helkid doubles as an off‑DPS.​
• Buffers and damage amplifiers
  • Lily, Gray, Beyontin, Kloss, Plume, and some DPS‑leaning supports like Heinrich and Turandot provide ATK, Crit, DEF‑, or other damage amplification effects.​
  • HellHades describes Kloss as an “underrated damage amplifier” giving DEF‑, speed downs, and even reducing incoming damage, making her ideal early/mid when raw stats are low.​
  • Enjoygm notes that Plume stacks ally damage via Curse Quill and applies DEF/Weakness debuffs, turning ramp DPS like Kokardi or Massiah into monsters.​
• Debuffers and control
  • Veronika, Celince, Kraken, Obol, Lilith, Dinah, RC‑77, and Marvell specialize in stuns, buff strip, DEF break, and ATK reduction.​
  • HellHades flags Kraken, Obol, Rin, Lilith, and Kloss as the core control units for CC‑focused teams, while Enjoygm calls Obol and Marvell particularly important in DoT and boss-control metas.​
• Revive / fail‑safe utilities
  • Beyontin, Sania (with certain builds), DokiDoki, and some niche supports bring revival or pseudo‑revive effects.​
  • Escapist’s guide emphasises that while keeping the team alive is ideal, revives from Beyontin and DokiDoki are invaluable backup in Aurora and other punishing content.​

Who to prioritise depending on your focus

Tier lists and “who to skill up first” style discussions give fairly clear upgrade orders.​

• If you want the safest all‑rounder core:
  • Build Lingluo and Freya as your primary sustain, then add Lily and Gray as main buffers; these four units are referenced in multiple sources as top, long‑term investments that rarely fall off.​
• If you’re pushing hard bosses (Aurora, Threshold, Union):
  • Prioritise Lingluo, Freya, Helkid, Celince, Veronika, Beyontin, and Kloss for sustain, mitigation, debuffs, and revives.​
• If you’re focusing on PvP/RTA:
  • Build Lily, Veronika, Beyontin, Celince, Lingluo, Helkid, Freya, and Sania, since they all appear at the top of PvP‑leaning tier lists and RTA breakdowns thanks to speed, cleanse, shields, revive, and buff‑steal.​​

Investing into these supports and healers early, then pairing them with a few top DPS, gives your account far more consistency than spreading resources across many mediocre damage dealers without the buffs, shields, and sustain to back them up.
