Bertha

Bertha is a Generation 17 Legendary Lancer whose hero-battle support combines healing with a brief offensive boost. Her medical career took a darker turn after she helped save a wounded commander who proved to be the bandit leader Zenobia. Bertha continued caring for the injured, but also began pursuing the people responsible for their suffering. Her oversized syringe weapon reflects that uneasy combination of treatment and punishment.

Healing Rain supports every allied hero

Healing Rain restores Health to all friendly heroes based on Bertha’s Attack, then raises their Attack for three seconds. At skill level 5, the healing is 280% of Bertha’s Attack and the temporary Attack increase is 25%. The skill therefore helps the team recover and creates a short period of stronger offense.

Tranquilizer deals damage to one target and immobilizes it for 1.5 seconds. Its level-5 damage is 140% of Bertha’s Attack. Enhancement Reagent improves Bertha’s own normal-attack damage, reaching a 30% increase at level 5. That is a normal-attack bonus, separate from the Attack stat used to scale Healing Rain.

Editorial recommendation: compare Bertha’s healing with the damage your team takes before and between casts. Her contribution is strongest when surviving heroes can use both the restored Health and the three-second Attack boost. Watch the team’s follow-up attacks as well as Bertha’s healing total when assessing a battle.

Adjudicator strengthens the opening

The exclusive weapon’s Serum Vitalis gives allied heroes increased Attack Speed and reduced damage taken at the start of battle. Both effects reach 15% and last ten seconds at the highest listed effect. This opening support complements the later healing from her regular kit.

Antibodies is the weapon’s Expedition effect, increasing Defender Troops’ Lethality by up to 15%. It supports a defending troop formation separately from Serum Vitalis and Healing Rain.

Expedition: Lancer attacks create pressure

Dissection supplies a formation-wide Lethality bonus. The other two skills make Bertha’s Lancers the trigger for additional effects. Vengeance adds a benefit for friendly Marksmen, while Lethal Precision applies a short damage-taken increase to the attacked enemy.

These are different offensive attributes: Dissection raises Lethality, Vengeance raises Marksman Attack, and Lethal Precision increases the target’s damage taken. Keeping them separate gives a clearer picture of what Bertha contributes to a march. The target vulnerability lasts one turn, while Vengeance follows its own every-second-attack trigger.
