concentration, 5 minutes/mana
As you spend 1 minute to cast this spell, you summon a pegasus, which appears in an unoccupied space that you can see within 20 meters. The celestial is friendly to you and your companions and disappears when it drops to 0 health or when the spell ends.
The celestial can’t use any legendary actions or lair actions. Any spell cast by the summoned celestial reduces your mana by the amount the celestial expends.
When it attacks, make a melee spell attack in place of its attack, but retain the damage and other effects.
Any creature you animated with this spell acts after your turn. You can mentally command the creature if it is within 20 meters of you (if you control multiple creatures, you can command any or all of them at the same time, issuing the same command to each one). The creature(s) will generally follow any specific verbal commands that you issue to them if the likely outcome is in accordance with its desires (no action required by you). For example you may command it to guard a particular chamber or corridor, explore the room ahead, or to attack a specific creature. If you don't issue any commands, they defend themselves from hostile creatures, but otherwise take no actions.
Augment
You can summon one additional pegasus for each additional mana.
