Build Bertha for team healing in Arena or Lancer-supported damage in Expedition—not because one ranking calls her mandatory. Her Exploration kit restores allies and buffs their Attack. Her Expedition kit instead increases Lethality, strengthens Lancer attacks and creates damage opportunities for the formation. Those are separate jobs with separate upgrade priorities.
Where Bertha Earns a Place
| Situation | Why she can help | Reason to delay investment |
|---|---|---|
| Your Arena frontline survives but cannot recover | Team healing can preserve an otherwise functional formation | Allies die before the heal; the immediate problem is survival |
| You lead a Lancer–Marksman march | Her Lancer effects and Marksman support have units to benefit | Your planned march barely uses Lancers |
| You mainly join rallies | Dissection is the relevant first-slot support skill | You are paying for other skills that this role does not contribute |
| You regularly defend structures | The defender-specific widget effect may fit your assignment | Your main activity is an offensive damage event |
Community discussions about rally composition emphasize that leader and participant builds are not interchangeable. As a joiner, your first hero's first Expedition skill is the candidate contribution, rather than all three heroes' entire kits. Before spending general shards, ask your rally captain whether Bertha belongs in the requested support lineup.
Arena: Upgrade the Heal, Not Just the Damage Number
Healing Rain restores all friendly heroes for 200–280% of Bertha's Attack and grants an Attack buff of 5–25% for three seconds. Tranquilizer deals single-target damage and immobilizes for 1.5 seconds. Enhancement Reagent increases Bertha's normal-attack damage by 10–30%.
Healing Rain is the first upgrade for a support build. It improves two team effects. Tranquilizer's control duration does not grow with its damage multiplier, so unlocking the control and buying more damage are different purchases. Enhancement Reagent improves her own attacks; it is not an Attack-stat increase that automatically makes Healing Rain stronger.
Arena combat is automated. You cannot promise to press Healing Rain immediately before a carry's burst. Instead, watch who receives the heal and whether that hero remains alive long enough to exploit it. If your frontline disappears in the opening exchange, moving Bertha into the lineup without fixing that frontline can simply replace useful damage with a heal that arrives too late.
A practical comparison is Bertha versus the support she would replace, with the same other four heroes. Look beyond the total healing column: did the heal preserve your main attacker, extend a losing fight without changing the result, or arrive when most allies were already healthy? These outcomes call for different upgrades.
Expedition: Her Value Depends on Troop Composition
Dissection raises allied squad Lethality by up to 25%. Vengeance strengthens every second Lancer attack and adds a one-turn Marksman Attack buff. Lethal Precision strengthens Lancer attacks and applies a one-turn Weakness effect. These effects do not turn Bertha's Exploration healing into troop healing.
For a captain with a meaningful Lancer component, prioritize Lethal Precision, then compare Vengeance with Dissection. Vengeance becomes more attractive when both its Lancer trigger and Marksman benefit matter. Dissection is the simpler broad contribution when your composition is less specialized.
For a rally joiner, develop Dissection for the selected support role. Do not use the captain's priority order and leave the one relevant contribution underleveled. Likewise, 25% Lethality and 25% damage dealt are different stats; matching percentages alone do not establish equal rally performance.
Adjudicator: Separate the Opening Buff from the Defender Buff
Adjudicator's Serum Vitalis supplies an opening Exploration effect: at its listed maximum, allies receive 15% Attack Speed and 15% damage reduction for ten seconds. Antibodies separately increases Defender troop Lethality by up to 15%.
The opening effect can address the specific problem of surviving until Healing Rain. The defender effect has a different audience: accounts assigned to troop defense. Do not add both effects together and advertise that combined package for Bear damage or city defense; the modes use different systems.
Fund the widget when its next displayed effect solves a job you actually give Bertha. A support used throughout Arena has a stronger case than a reserve hero who only fills a spare march. There is no evidence-based universal requirement to stop every Bertha at widget level seven.
Gear and Shards: Avoid Paying Twice for a Replacement
Player gear discussions favor Lancer Goggles and Boots when offensive troop value is the goal. Bertha still needs enough personal durability for her Arena assignment. Start with an existing Lancer set when comparing her with your current hero, then decide whether she deserves the permanent transfer. Do not build two expensive sets merely to make the comparison.
Her listed shard routes include King of Icefield, State of Power, Daily Deals, Hero Rally, general Mythic shards and the Foundry Shop. She is not listed as a Lucky Wheel hero. The final four-to-five-star stage costs 600 shards, so establish the obtainable event and shop supply before committing general shards to that finish.
For a limited-spending account, the key question is whether Bertha fills a missing role. If your Arena support already works and your rally role does not need her, unlocking another hero does not oblige you to complete her. Compare that expense with the Infantry or Marksman upgrade your main formation is still waiting for.
Frequently Asked Questions
Does Bertha heal troops in rallies?
Healing Rain belongs to Exploration. Her Expedition skills provide troop combat buffs instead.
Does leveling Tranquilizer increase the immobilize duration?
No. The listed duration stays at 1.5 seconds while the damage multiplier improves.
Does Enhancement Reagent strengthen her healing?
It increases normal-attack damage, not the Attack stat used to calculate Healing Rain.
Should a rally joiner follow the same skill order as a captain?
No. The joiner should fund the first Expedition skill needed for the selected contribution.
Is Bertha automatically worth five stars?
No. Her place in your active formation and your remaining shard supply should justify the final 600-shard stage.
