Fecund Growth

A bright green burst of energy emanates from the caster, causing all living entities, including plants, insects, and animals, to undergo tremendous growth. All plant life, including trees (but not plant creatures, see below), triple in size, along with new growth emerging from the ground, over the course of 3 rounds.

In addition, flowers bloom, crops reach their full growth, and trees bear large, nourishing fruit. Fruit, berries, and nuts picked from a fecund area provide the same benefits as a goodberry spell for one day per level of the caster – after that time, the fruit falls off the tree, losing all magical properties. Once the duration of the spell ends, the plants resume their normal cycle of growth.
Any creature (including insects and vermin) with an Intelligence score of 2 or lower doubles in size, as if affected by an animal growth spell. In addition, they increase by one age category (if applicable). A newborn animal, for instance, ages to adolescence. Normally, harmless creatures remain as such, just bigger. Sentient creatures are allowed a Fortitude save. Failure indicates that the creatures increase in size as if affected by an enlarge person spell, lasting 1 hour per level of the caster.
In addition, the creature must make a second Fortitude save. If it fails, the creature ages by one age category, which may affect their ability scores.
