Casting Time 1 round
Components V, S, DF
You summon a school of hippocampi (one plus one per 3 caster levels, to a maximum of six at 15th level) to serve as combat-trained mounts. the hippocampi avoid combat if possible but defend themselves if attacked. If any hippocampus attacks, the remaining duration of the spell changes from 1 hour per level to 1 round per level (so if a full 4 hours remained, the hippocampi last for only 4 more rounds).
