Daniela Dimitrescu

Chapter: 4 · Castle Dimitrescu
Where: The Library (2F): round, with pillars in the middle, bookshelves and a glass dome. Opened with the Iron Insignia Key from the Opera Hall's 2F.

Weak point

The cold from the dome, which a lever opens. Same factors as Bela: ×2.0 from handguns, rifles and magnums; ×1.6 from shotguns.

She attacks as soon as you walk in. She uses the swarm far more than her sisters: her flies block your view, especially while you block, and she teleports close or floats at you to strike or bite.

Open the dome with the lever, shoot her from range while the cold is in, and go back to the lever every time it closes.

Reward

Crystal Torso (5,000 Lei). Head west into the Hall of Joy for the Mask of Joy.

3,700 HP. Rough estimate at Standard's starting rank: about 37 un-upgraded LEMI shots or 9 M1897 blasts.

Village of Shadows: same plan with a little more damage taken; an infinite-ammo magnum ends it quickly.

Step by step

Run straight to the pillars in the middle: one has a lever that opens the dome and lets the cold in for a while. Don't shoot the ceiling: the glass won't break.
With the dome open, shoot her from range. She runs and hides behind the bookshelves: don't close in even when she looks weak.
Circle the room and collect ammo: Handgun Ammo ×10 on the south bookshelf and ×10 on the north-west dresser, Shotgun Ammo ×3 on the north-east bookshelf.
When you hear the mechanism clink, the dome is closing: go back and pull the lever again.
