Which attacks should you distinguish first?
Carmilla’s encounter is in Observatory, Library. Her active attacks include summoned skulls, moving skulls, blood spikes or pillars, and a dive. These are distinct attacks: do not assume that avoiding the first skull also clears the floor or ends her approach.
As a positioning suggestion, keep both the floor and the space above it in view. Move out of a marked ground threat before choosing where to attack, and avoid committing to a long stationary action while skulls or a dive are approaching.
What changes near the end of her health bar?
At about 22% remaining health, Carmilla can enter her final attack sequence. Its successive attacks move from the left side to the right and then the middle, mixing blood pillars and spikes. Follow each new attack rather than moving once and treating the rest of the sequence as safe.
During the final sequence she is temporarily kept alive at 1 HP. Preserve space and resources through the sequence instead of repeatedly trying to force the last point of damage. Resume the finish when that sequence has completed.
What does the reward orb give you?
After defeating Carmilla, interact with the reward orb to receive The Occultist and Blood Spikes. Blood Spikes is the spell called Blood Spikes in the equipment menu; the later Aerial Rush tutorial is a separate unlock.
For the spell’s bleeding-kill Work of Mercy, the bleeding damage needs to defeat the target. Applying bleed and finishing with a weapon does not satisfy that stated condition. Compare its tasks and upgrades before choosing your next group of enemies.
How do you unlock Aerial Rush after Carmilla?
Defeating Carmilla is the prerequisite for the Aerial Rush tutorial room in Library. Go to the tutorial room linked below and complete that interaction. The boss marker identifies Observatory; it is not an extra ability pickup marker.
Use the ability entry for its controls and tutorial-room reference, then revisit a branch where aerial movement will help. Keep this unlock separate from the spell reward when checking what you still need to do after the fight.
