Finding arcane connections to oneself

[OneShot]

There is a useful old discussion on this forum with many authors, which helps to better understand ArM5 p.84: "Mystically, the Arcane Connection is still a part of the target, thus making the spell possible." Access to such threads makes the retrieval of this forum so very valuable.

We find there:

Arcane Connections are formed according to two laws: the Law of Sympathy and the Law of Contagion. That is, they either mystically resonate with the target, or they were once part of the target. The latter case is primarily what we're concerned with here, and a common example is a hair from a person's head. A hair from my head was once part of me, so it is an Arcane Connection to me because of the Law of Contagion. I was never part of the hair that came from my head, so by that same Law I am not an Arcane Connection to it.

In particular, an AC to the caster is not necessary an (ArM5 p.112f) Part of her, or can be targeted by her using a spell with Range (ArM5 p.111) Personal.
