Encounter phases

Adventure Guide says

1. Primal Anima Containers Anima containers are placed around Lady Inerva Darkvein's balcony that gradually gather anima energy to empower each of her abilities. Players can interact with the containers to open them, and close them by interacting with them again. Open containers vent their Loose Anima into the playspace. When any container reaches full capacity, a Container Breach occurs. The breach continues to damage players until the anima level is reduced below capacity.
2. Container of Desire The Container of Desire governs the power of Lady Inerva Darkvein's Expose Desires ability. As the container increases in level, the power of Expose Desires increases. Lady Inerva Darkvein uses these abilities when she reaches 100 energy.
3. Container of Bottled Anima The Container of Bottled Anima governs the power of Lady Inerva Darkvein's Bottled Anima ability. As the container increases in level, the power of Bottled Anima increases.
4. Container of Sin The Container of Sin governs the power of Lady Inerva Darkvein's Sins and Suffering ability. As the container increases in level, the power of Sins and Suffering increases.
5. Container of Concentrated Anima The Container of Concentrated Anima governs the power of Lady Inerva Darkvein's Concentrated Anima ability. As the container increases in level, the power of Concentrated Anima increases. Each cast of Concentrated Anima results in one Harnessed Specter. Any additional players chosen for this ability cause a Conjured Manifestation to appear.
