This ritual blesses its willing or unwilling subject to be an avatar through which Shub-Niggurath can manifest herself. If after the ritual is concluded, the avatar is in an area currently affected by the obscene fertility rites of Shub-Niggurath, Shub-Niggurath may burst forth from the avatar at influence stage 3, effectively slaying it.
Alternatively, a dark young or acolyte of Shub- Niggurath can magically command the avatar to bring forth the Outer God at any time as an action over the course of 1 round with a successful Profession (Yog-Sothothery philosopher) check against DC 40.
Shub-Niggurath will then remain at influence stage 3 until her whims draw her elsewhere or she is defeated or banished somehow. Unless Shub-Niggurath would otherwise be at influence stage 3, she falls back to influence stage 2 when her nucleus is destroyed. Only a wish, miracle, or similarly powerful magic can remove this blessing, and even then, the caster must make a caster level check with a DC of 37.
