As a Bonus Action, you can cause a "dust" cloud. The dust last for 1 hour or until you dismiss them (no action required). For the duration, you have a Fly Speed of 60 feet.

Once you use this feature, you can’t use it again until you finish a Long Rest unless you spend 3 Sorcery Points (no action required) to restore your use of it.

You can cast Summon Dragon without a Material component. You can also cast it once without a spell slot, and you regain the ability to cast it in this way when you finish a Long Rest.

Whenever you start casting the spell, you can modify it so that it doesn’t require Concentration. If you do so, the spell’s duration becomes 1 minute for that casting.
