Underrated Characters You Should Build

In Etheria: Restart, it’s easy to get swept up chasing the latest Light/Dark powerhouse or stacking your roster with meta-defining SSRs. But here’s the truth, some of the biggest progression boosts can come from units you’ve probably ignored, benched, or even dusted off with a sigh after an unlucky pull.

Today, we’re diving deep into underrated SSRs and SRs that can make a huge difference in both PvE and PvP. These characters might not dominate tier lists, but when built right, they can completely change how you play the game.

Etheria: Restart makes you think carefully about resource spending. Lattice upgrades are rare, and building the wrong unit can set you back weeks. This leads to herd mentality, the community praises certain heroes while quietly dismissing others. But many of these “trash” units? They’re actually hidden gems waiting to shine in the right team.

DokiDoki – The Tactical Turn Booster

Once written off as mediocre, DokiDoki is now appearing in more and more top-tier teams. Her turn meter boost and Data Stream buff give your squad enhanced stats, damage amplification, and debuff cleansing. The catch? She can’t target allies manually. Her buffs go to the most eligible unit based on cooldowns or turn meter. Still, in both PvE and PvP, this is game-changing.

Best of all, she works without Lattice, meaning you can gear her with Codex or Time/Swift sets and still dominate. In PvP, she’s a nightmare, one speed push can let you cut in front of the enemy and turn the match in your favor.

Tsukiyo Mi – The Budget Lily That’s More Than a Budget

Often dismissed in favor of Lily, Tsukiyo Mi is a speed demon who decreases cooldowns, applies Silence with enough accuracy, and massively pushes turn meter for your top attacker.
In PvP, building her as your fastest unit allows explosive openers — think speed buff + attack boost straight into a nuker’s big hit. In PvE, she’s just as valuable, especially in shell dungeons and control-heavy fights.

Yes, Lattice shortens her cooldowns, but even without it she’s a monster in progression and endgame content.

Mia – The PvE Control Queen

Mia is the definition of “don’t believe the tier list hype.” She brings dispel, turn meter reduction, healing, buff extension, and cooldown reduction. In fights like Permaton or tough shell bosses, she can single-handedly control the pace.
She’s not a PvP star, but for PvE? She’s a top-tier support that too many players ignore.

Rin the Unbowed – The Speedy Arena Harasser

Rin’s high base speed makes her a great choice for opening in PvP. She brings AoE speed up for your team, scales damage with her own speed, and applies speed down to enemies. She won’t one-shot, but she’ll soften targets for your follow-up damage dealers.

RC77 – The Control Specialist

At 128 base speed (faster than Lily), RC-77 can open with stuns, attack down, and defense down in a single skill. This combination is brutal in PvP for shutting down key threats, but it’s also excellent in PvE for boss fights where survival and damage amplification matter.
He can also extend debuffs and manipulate turn meter, making him a versatile asset.

Kazami Kazuyo – The AoE Cooldown Reducer

In some teams, Kazami outshines Lily. Instead of reducing cooldowns for just one ally, she does it for the entire team — letting healers heal more often, debuffers maintain uptime, and damage dealers cycle nukes faster. She can also strip enemy buffs and increase their cooldowns.
As an SR, she’s easier to skill up, making her a smart investment.

Yang – The Free Utility Buffer

Yang might be the weakest on this list, but for players without top-tier SSR buffers, he’s an easy-to-obtain support. He provides attack up and crit rate up, along with a small turn meter boost on crits. He’s replaceable later, but a solid budget option early on.

We’ve all been wrong before — take Nahor, for example. Initially hyped as overpowered, players soon realized his crowd control didn’t work on most dungeon minions. He’s not useless, though — in content like Infinity Train, Trial Challenges, and upcoming modes like Cage Rumble, he could still be incredible.

The moral here? Don’t blindly follow early tier lists. Many “low-rated” characters become stars in the right context, and in Etheria: Restart, team synergy and smart building matter more than pure rarity.
