Arcanonaut

Jump. If Arcanonaut moves at least 30 feet in a straight line, it can clear a distance of up to 60 feet when jumping over a chasm, ravine, or other gap. Each foot it clears on the jump counts as a foot of movement.

Magic Weapons. Arcanonaut's weapon attacks are magical.

Repairable. As long as it has at least one point remaining, Arcanonaut regains 1 hit point when a mending spell is cast on it.

Prone Deficiency. If Arcanonaut falls prone, it can't right itself and is incapacitated until pulled upright.

Stunt. On it's turn the driver of Arcanonaut can expend 10 feet of movement to perform one free vehicle stunt, such as a wheelie or a burnout. Before the stunt can be performed, Arcanonaut must move at least 10 feet in a straight line. If the driver succeeds on a DC 10 Dexterity check using the bikes Dexterity, the stunt is successful. Otherwise, the driver is unable to perform the stunt and can't attempt another stunt until the start of it's next turn. If the check fails by 5 or more, Arcanonaut and all creatures riding it immediately fall prone as the bike wipes out and comes to a dead stop.

Juke. If Arcanonaut is able to move, the driver can use it's reaction to grant Ember's Ride advantage on Dexterity saving throws..
