This spell is a specialized variation of the 4th level priest spell animal summoning I. By means of this spell, the caster calls a number of cetaceans (such as dolphins, porpoises, and whales), whose combined Hit Dice total 32 or less. Dolphins are always summoned first if available. Otherwise, if more than one species is available, the type with greater Hit Dice is summoned. Only cetaceans within a mile of the caster at the time of the casting will respond.
Unlike the animal summoning 1 spell, the caster can make only one call, and cannot choose what form of cetacean shows up, if any. The cetaceans summoned aid the caster by whatever means they possess, staying until the fight is over, a specific mission is finished, the caster is safe, they are sent away, and so on.
Notes: Granted by the elven god Deep Sashelas.
