When a shadowrunning team tries to break into a facility protected by magic, it seems to me as a GM like the team's biggest liability is getting past magical security. If a mundane B&E character tries to use Infiltration to get up close to the facility, a watcher spirit, bound spirit, or astrally projecting security mage can spot them, because they're lit up like a torch in the astral plane.
This gives rise to closely-related questions:
- As a GM, how should I handle stealth vs. a spirit or astral projection? Should I make the astral being roll Perception (or Assensing?) against the stealthy character's Infiltration? Is it possible for the character to be stealthy without a spirit providing the Concealment power?
- If the observing entity is a spirit, is there a way for the intruding team's mage to misdirect the spirit so that the intrusion goes unnoticed?
- How can a mage on the intruding team go unnoticed when astrally projecting to scope out the site?
