Your stench is overwhelmingly nauseating.

Prerequisite(s): Stench universal monster ability, Improved Stench, Great Fortitude

Benefit: The first round a creature is affected by your stench, it is nauseated in addition to being sickened. At the end of an affected creature's turn after the first round, it can make a new save against the stench's DC to remove the nauseated condition, but the sickened condition lasts as long as normal.
