Invisibility, Greater

==Description==
The target creature becomes invisible and impossible to detect using normal vision. After attacking or casting spells the target creature will become partially visible and detectable by enemies, but treated as having 50% concealment.
Assassins gain Greater Invisibility at 9th level. The duration for Assassins is 1 round per casterlevel, instead of 6 seconds.
==Notes==
