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.
