Level 3 (complex)
Components V, S, M
Area 10-ft.-radius emanation around the creature

This spell functions like invisibility, except that this spell confers invisibility upon all creatures with-in 10 feet of the recipient at the time the spell is cast.

Those affected by this spell can see each other and themselves as if unaffected by the spell. Any affected creature moving out of the area becomes visible, but creatures moving into the area after the spell is cast do not become invisible. Affected creatures (other than the recipient) who attack negate the invisibility only for themselves. If the spell recipient attacks, the invisibility sphere ends.
