Best Shells for CBT 4

In Etheria: Restart, Shell Companions are the unsung heroes quietly supercharging your Animus teams behind the scenes. From passive turn meter boosts to powerful support effects, the right Shell can dramatically shift the flow of battle. With CBT4 introducing a full lineup of Shells—from rare starters to legendary game-changers—it’s time to dive deep into which ones are worth your investment and when to use them.

Let’s break down every Shell Companion tiered in CBT4, explaining what makes each one tick and where they shine in early, mid, and late game.

These are your basic Rare Shells—limited in gear compatibility, capped at level 20, and really only here to get your feet wet.

Red Comet

Heals and buffs attack before action, but is locked into Onslaught gear (attack set). Quick to fall off.

Scorpion Queen

Offers basic healing to the lowest HP allies, but limited to Wellspring (HP set) and lacks long-term utility.

Phantom Cat

Slightly better thanks to bonus crit damage on follow-up hits, but still shackled by Onslaught-only synergy and weak scaling.

Verdict: Nice to test with, but don’t invest resources long term.

The Unique rarity Shells (max level 30) introduce more variety and better gear compatibility—often solid for the midgame or until you get something stronger.

Agent Lizard

Early nuker with damage scaling and low-HP targeting. Has Onslaught and Swift Rush options.

Teacher Owl

Boosts healing output by a flat 2000, solid for beginner support builds.

Tamamo Doji

Entry-level DPS Shell that buffs ATK and Crit Rate. Versatile for Onslaught, Cure, and Harvest sets.

White Gale

Applies damage and increases Effect Accuracy, helpful for control builds.

Reason

Pre-turn healing boost + Heal-over-Time if ally is below 65%. Accessible healing sets and solid early utility.

Verdict: Great stepping stones. Use until you pull higher-rarity Shells.

These Shells are highly impactful in both utility and synergy, offering essential boosts that can carry you well into mid-game and even early endgame content.

Unbridled Science

A sleeper MVP. Increases strike prep (turn meter) by 40% after your turn—game-changing for speed-tuned teams.

Mermaid Princess

The only early-game Shell that purifies up to 3 debuffs before action. A lifesaver in control-heavy content.

Budo Panda

DPS-friendly with crit follow-ups and stacking crit damage. Solid synergy with free units like Gray who boost Crit Rate.

Star

Reduces skill cooldowns and adds strike prep. Huge for teams lacking maxed-out skill levels.

Verdict: These are the Shells you’ll want to invest in early and possibly carry into late-game.

Epic Shells are where power truly ramps up. They scale better, support more Matrix sets (4 per Shell), and become pivotal parts of your team composition.

Blizzard

Reduces random skill cooldowns after action with great Matrix flexibility (Def, Speed, Counter, Immunity).

Black Flag

Boosts speed and strike prep after action with a strong follow-up hit. Supports speed rotations extremely well.

Shan Hai Jing

Gains 25% turn meter per 3 enemy actions. Scales with enemy movement, great for reactive comps.

Twilight Knight

Striker Shell that hits lowest-HP enemy pre-turn and applies massive 60% defense break.

Crossroads

Grants Lifesteal and ATK buff. Only Shell offering Life Leech—essential for sustain DPS builds.

Diamond Heart

Provides Defense Up and a huge shield—especially busted with defense-scaling units like Rahu.

Electro Squid

A better version of Reason with stronger healing and better gear support, including Immunity and Speed sets.

Verdict: These Shells offer major team-wide impact and are often endgame viable.

Now we’re in the realm of pure power. Legendary Shells (Level 40 cap, maximum Matrix synergy) are the top of the top—but don’t expect to get them easily in official release.

Supernova

Best healing Shell in the game. Huge healing buff, HoT, and access to all top healer sets.

Law of Silence

Applies Void state (camouflage) to prevent targeting and reduces AoE damage. Reapplies every 4 turns. Ridiculous for PvP and protecting key units.

Golden Lion

Increases Crit Damage and Effect Acc with no cooldown. Stacks up to 5x. Great for damage scaling without needing raw Crit Rate stats.

Alicorn

Cleanses up to 3 debuffs and heals 10% HP for each removed. Unmatched sustain and debuff management.

Codex of Magic

The most broken Shell Companion in the game. Negates skill cooldown cost—use any skill twice in a row. Game-defining value for nearly any unit.

White Fang

Upgrades Budo Panda with crit damage stacking and better follow-up damage.

Gigabyte

Turn meter booster that outpaces Science. Triggers per 3 enemy actions for massive rotation potential.

Verdict: These are the dream Shells. Build your endgame around them when you get the chance.

Shell Companions in Etheria: Restart aren’t just passive bonuses—they’re core to your progression and success. Early on, stick with flexible Unique Shells and aim to transition into the S and SS-tier Epics. Once you reach the late game (or get lucky in CBT pulls), chase the SSS-tier Legendaries to supercharge your comps.

Looking for early-game help? Mermaid Princess, Unbridled Science, and Star are clutch picks. For long-term investment, Blizzard, Black Flag, and Diamond Heart offer incredible value until you can chase the almighty Codex of Magic.

Pro Tip: Don’t just look at the Shell’s skill—pay close attention to the Matrix combinations available. The right set synergy can turn a good Shell into a game-winner.
