Affect Substantial

Affect Substantial (B63: only two Ss) is a +100% enhancement for Insubstantiality
*not to be confused with B102's +40% enhancement Affects Substantial (three Ss) for Innate Attack
The similarity in the names has resulted in mixups/typos in later books. For example in GURPS Psionic Powers pg 14:
:"Substantial Communication: This is a weaker version of Affects Substantial (+100%)."
:They take the standard -3 to skill unless they have the Affects Substantial (+40%) modifier."
Substantial Communication introduces the idea of putting the word "Substantial" out front, which is more distinct. The remaining +60% could be thought of as being able to attack in addition to communicate, so collectively it might be called something like "Substantial Affecting".
