-   At the end of hour 2, they gain advantage on all saves vs magic and all saves vs psionic / mental powers, along with the following psionic power (which can be used 3x per day):
    -   **Bolt**: Target within 60' must **Save vs Spells** or take 3d6 damage.
-   At the end of hour 3, they gain the ability to make an attack with each tentacle for 1d2 damage (plus the chance to perform a [Brain Grab](#brain-grab)), and the following psionic power (which can be used 3x per day):
    -   **Control**: Target within 30' must **Save** or come under the mental control of the master vampire neurovore for 1d6 rounds.
        -   Target gets additional save to break the control when forced to commit acts that are against their alignment or self-destructive.
