DESCRIPTION

This powerful ritual channels the fecundity of Shub-Niggurath to an area, which gives Shub-Niggurath influence stage 2 over the area for the duration. Crops are lusher, beasts and humanoids breed more easily and quickly, and fertility increases significantly in general. Additionally, 50% of all creatures born are mutated in some way. This may be simply be a strange appearance and a Mythos taint that grants a bonus on ritual skill checks, or as extreme as being a Mythos satyr or having the half-fiend template. Each of the ritual’s focus pillars is Huge, with hardness 8 and 600 hit points. If a pillar takes 300 or more points of damage, it is unusable for the ritual (and the ritual fails). During the ritual casting, the first time a pillar is damaged in some way, a dark young of Shub-Niggurath emerges from the woods or wilderness within 300 feet to defend it and kill any interlopers. This can occur once for each pillar.
