Apparition

Apparition is used to describe two different traits in 4e. In Classic: Undead it is another name for Ghost (Meta-Trait)
==GURPS Fantasy==
Apparition allows one to become visible but requires 1 FP each second. It is regarded as a Spirit Trait but actually works more like a +2 Lens:
*Invisibility (Usually On, +5%; Substantial Only, -10%) [38] replaces Invisibility (Substantial Only, -10%) [36] for a total of [2].
===D&D Lens===
Based on Lord Rasputin's version on GURPS Repository
*D&D Will-o-Wisp Lens [+200]: Add 360° Vision [25]; Combat Reflexes [15]; Dark Vision (Color Vision) [30]; Flight [25]; High Pain Threshold [10]; Immunity to Metabolic Hazards [30]; Indomitable [15]; Invisibility (Switchable +10%; Substantial Only -10%) [40]; Magic Resistance 10 [20]; No Legs (Aerial) [0] ; No Manipulators [-50]; Silence 5 [25]; Unfazeable [15].
