==Special Modifiers==
===Special Enhancements===
*True Sight (+50%): "vision can penetrate all deceptions related to the type of invisibility you can foil, including camouflage, disguises, and illusions."GURPS Powers p 73
===Special Limitations===
*Exclusive from PP17 is actually two categories:
**Partially Exclusive
**Completely Exclusive
==Forms==
* See Invisible (unparenthesized) is suggested on P127 for Electrokinesis and ESP, P129 for Illusion, P130 for Light
**presumably when no source/category/type is specified this defaults to mean Electromagnetic Vision, or it could mean that any variety could be purchased reasonably under the power
* See Invisible (Ghosts) is suggested under Astral Projection power on P123, and P134 for Spirit Control
**this is a descriptive category, per Horror
* See Invisible (Magical) is suggested under Anti-Magic GURPS Powers pg 121
* See Invisible (Psionic) is suggested under Anti-PsiGURPS Powers pg 122
* See Invisible (Spirit)
**this is a power source, per Horror
* See Invisible (Super) is suggested under Anti-Super
P72 expanded with a new option:
"must choose either one of the descriptive categories under Invisibility (p. 56) or a particular power source"
"
H18 mentions the need to specify either:
*type of perception (ie Sonar)
*power source (ie Spirit)
*descriptive category (ie Ghosts)
"If he selects a source, then all that matters is the power modifier on Invisibility"
H39 the Mystic Practitioner includes "See Invisible (any)"
H75 the Minion includes "See Invisible [15]"
H82 the Witch includes "See Invisible (Spirit) [15]"
==Ghost problems==
Since spirits are often insubstantial in addition to being invisible, they can easily jump through (or into) walls/floors to use as cover to obstruct sight.
To adapt to that would require other countermeasures, such as:
*Clairsentience (advantage): using Clairvoyance to teleport one's vision to other localities, skirting cover
*Scanning Sense (to detect spirits behind cover)
*Penetrating Vision
==Alternatives==
*forms of invisibility which are Substantial Only (effectively give See Invisible for free to Insubstantial creatures)
*Senses that detect something else such as Sonar or Vibration Sense
*Dark Vision (Hypersensory enhancement)
*Blind Fighting skill: fight invisible foes without seeing them
*take Affects Substantial on Night Vision or Dark Vision, per B118 Spectral Vision metatrait.
