Automatic Helm

You touch a wildjammer Helm and grant it the limited ability to fly without a Helmsman. For the duration, the wildjammer flies in a straight line. If there are crew ready to work the sails, the wildjammer has 45º maneuverability. If it encounters obstacles, it will do its best to avoid the obstacle and then correct course. If the wildjammer has to make an ability check or saving throw, it rolls a flat 1d20.

At Higher Levels.
When you cast this spell using a spell slot of 3rd level or higher, the duration increases to 12 hours
