1 hour/mana
As you spend 1 minute to cast this spell, a Large quasi-real, horselike creature appears on the ground in an unoccupied space of your choice within 5 meters. You decide the creature’s appearance, but it has smoke-colored, insubstantial hooves that make no sound and it is equipped with a saddle, bit, and bridle. Any of the equipment created by the spell vanishes in a puff of smoke if it is carried more than 2 meters away from the steed.
For the duration, you or a creature you choose can ride the steed. The creature uses the statistics for a riding horse, except it has a speed of 20 meters and can travel 15 kilometers in an hour, or 25 kilometers at a fast pace. When the spell ends, the steed gradually fades, giving the rider 1 minute to dismount. The spell ends if you dismiss it on your turn (no action required) or if the steed takes any damage.
The steed can ride over sandy, muddy, or even swampy ground without difficulty or a decrease in speed.
Augment
You can create two additional steeds for each additional mana expended.
Water Steed. You can expend 1 additional mana so the steed can walk on water (per the water walk spell).
Flying Steed. You can expend 1 additional mana so the steed can fly at its speed.
