I am trying to figure out whether adepts using their magical powers leave an astral signature.
So far, since checking the core rulebook and Streetmagic, I have found a few forum discussions on the topic and the statement that it is only ambiguously defined in the core rulebook from before SR4A. I read an interpretation that the signature is only on themselves, as most of their magic is focused inwards. There were different positions on whether that holds true for magic that influences others such as Killing Hands and how to determine the duration until the signatures wane.
I am trying to find rules or official statements concerning:
- Do adept powers leave astral signatures at all?
- In case they do, what are signatures left on (the adept themselves, locations, touched objects, victims)?
- Is this different for different powers e.g. Improved Ability vs Killing Hands, i.e. skills that are in use at all times vs skills that have specific targets?
- What is the rule to determine how long the astral signatures last?
I have found plenty house-rules, I am solely interested in finding out whether there are official rules that I missed.
