walk unseen
Class: warlock : 2
Syntax: cast CLASS walk unseen

This invocation places illusory spellcraft around the warlock, deceiving the eyes of those around so as to effectively disappear from view. While minor, a small degree of concentration is required to maintain the effect, so it can become wearying over time. Becoming engaged in combat is sufficiently distracting to lose control of the concealment; also, falling unconscious will cause the invocation to fail. Of course, the warlock can simply forgo the concentration to <appear> at any time.
