Swarm (enhancement)

Swarm (not to be confused with swarms) is a P53 enhancement for Diffuse which includes Infiltration
It came in two forms priced at +80% or +160%
GURPS Horror pg 14 abandoned the Swarm enhancements and split them into components:
*Body of Swarm +0% (a 0pt feature in Toolkit 2
*Infiltration +40%
*Scatter +40%
**another +80% (total +120%) to affect material world while scattered

:When I wrote, "treat this state as Insubstantiality," I meant it.
:You can drift upward or downward at full Move, as for Insubstantiality.
:The value of Swarm is +80% against a 100-point advantage for a good reason:
:it costs 80 points,
:which is identical to the cost of Insubstantiality,
:which it emulates in most regards.
20 MAy 2013 post from the matrix walker:
: I am of the opinion that the intent is that a dispersed swarm character would need affects insubstantial on any ability they wanted to use on the substantial world.

:Since the difference between the +80% and +160% is specifically meant to generate an 80-point cost that mirrors the effect of Affect Substantial, +100% on Insubstantiality, I would have to agree with you. Obviously, no extra enhancement is needed on senses or movement abilities, as they clearly work regardless . . . but attacks and such would be rather overpowered if not balanced in some way.
