Even with severe limitations on it, the result is unlikely to be cost-effective.

It's something I vaguely thought about, but not in enough detail. I pretty much put it in as an afterthought because the idea was there. I'm sure there's a better option for 'things tend to miss you, even if you don't know they're coming and they're not being aimed' (other than just using the Path/Book Magic system) but I'm not sure what. I recall someone writing up a variant of Obscure that instead of having Anti-Targeting or being Obscure to any sense was 'Obscure to projectiles,' which I found jarring.

The only thing I'd add is that you might want to look at the optional rules for Spirit powers found in GURPS Powers — not because this is a spiritual power, but because those modifiers are designed with the sort of feel that a GURPS Horror “mancy” ought to have. I'm referring specifically to the Ritual Modifiers found on Powers page 178: Affecting Others, Consecration, Regalia, and Ritual Length.

Thanks. I'll try to look in Powers when getting to my copy is less inconvenient... or I'll just get it anyway.
