Since Andovar is interested in information, he likes to know how many people are around. This spell helps him know when he's actually gotten a chance to talk to everyone.
Pulse of the Hearth and Home (Intellego Mentem 15)
R: Touch, D: Concentration, T: Structure
The caster can detect the number of minds in the building. The minds each have a unique sense - usually dictated by the caster's sigil - but they are not actually identifiable as individuals.
(Base 2, +1 Touch, +1 Conc, +3 Structure)
Design notes: Base from TMRE p93. Useful for figuring out how many people are around. One could instead consider a Room target with a +1 size so you could check a room for hidden individuals.
