Versatile Frontline DPS
Strong in both melee and ranged combat, Berenica can clear enemy waves and deal sustained DPS efficiently. However, her high damage depends on combo timings and Sanity consumption.
Has Hit-stun Immunity with Netherflames
When Berenica activates Netherflames, she becomes immune to hit-stun, allowing her to keep attacking even under enemy fire. This allows her to maintain control in melee combat, making her highly effective against bosses with frequent knockback attacks.

Berenica Best Weapon
Berenica's Best Melee Weapon
| Best Melee Weapon |
|---|
Wanewraith |
Berenica's Consonance Weapon benefits primarily from character stats, making the Skill DMG bonus from Wanewraith very effective whenever she enters her ultimate state, as well as when she uses her dash. If you have enough skill damage from other sources, you could also equip a Remanent Reminiscence for maximum ultimate uptime.
Berenica's Best Ranged Weapon
| Best Range Weapon |
|---|
Blast Artistry |
Blast Artistry functions as a stat stick that grants Berenica Skill Efficiency so that she can maximize her ultimate uptime. Otherwise, you could equip Bluecurrent Pulse or Excres Duo depending on your build.

Blast Artistry |
Blast Artistry is Berenica's BiS as a Combat Partner since you will want to give the AI as much room as possible for them to use Berenica's abilities.

Berenica typically focuses on wielding [Ymir] whenever she wants to deal damage, which makes Excresduo another stat stick
that is slotted only for the increased Skill DMG. Therefore, a generic ranged weapon build will work well enough in most cases.
