This spell summons a natural creature. It appears where designated and acts immediately, on the caster's turn. It attacks caster's opponents to the best of its ability. If caster can communicate with the creature they may direct it not to attack, to attack particular enemies or to perform other actions.

A summoned monster can not summon or otherwise conjure another creature, nor can it use any teleportation or planar travel abilities. Creatures can not be summoned into an environment that can not support them. For instance, a porpoise may only be summoned in an aquatic environment. Creatures in the Summon Nature's Ally tables this colour may only be summoned into an aquatic environment.

The spell conjures one of the creatures from the 2nd-level Summon Nature's Ally Table, or 1D3 creatures from the 1st-level Summon Nature's Ally Table. The creature type is chosen and must all be of the same kind, but can be changed each time the spell is cast. All the creatures on the table are neutral unless otherwise noted.
