Once they smother and kill a target, they work their way into their mouths and nasal passages down into the target's lungs to absorb the remaining life-force and residual heat. Cutting them with blades merely divides them into smaller versions, releasing a good deal of heat energy that washes over the target, causing low levels of heat damage. They can be contained in air- and water-tight containers and will become dormant and can be hid away and disposed of but they take no damage from heat-based attacks and these only make them larger. They may be drawn away from targets by a fire of sufficient size; clerical turning may disrupt them and cause their hateful forms to disperse for a time.
Should a living thing die from the attacks of Noctules, the Noctules will invade the lungs or similar organs and reproduce there, 1d10 more Noctules emerging a day later at dusk
