Assensing basically yields information in four important fields, the depth depending on the number of successes:
- magical capabilities and phenomena: it tells if a person is able to use magic, how strong and possibly what type of user she is, and if there are active magical effects or astral signatures present
- physical health: tells if a person is wounded, intoxicated, under the influence of some substance, etc.
- emotional state
- presence and location of cyber/bioware
Of course, these can be interpreted in a wide variety of ways, because the book doesn’t tell how exact information you get. As a GM, I tend to consider the number of successes rolled to the number needed to get the actual piece of information and I give out more details the more hits the assensing character has above the needed level. For example, presence and location of (non-graded) cyberware implants requires 2 hits. If the character has 2 hits, I give a vague description (like “probably some headware”). If the character has 5 hits, I usually give him detailed info (like “he has a datajack and his eyes are replaced”).
Actually, what I consider the most important category is the emotional state. As a baseline, it only requires one success. I don’t expect to be able to analyze the complex emotional state of a person at a glance, but I’d like to ask you to always include at least some indication of this if I do a successful assensing on someone.
@Xilostacia: I tried to compose my answer using the Sperethiel dictionary I found on the net but it is somewhat lacking in vocabulary. But it was cool that you did it that way.
