Timeless Engine

7th-level transmutation (clockwork)

Casting Time: 1 action

Range: Touch

Components: V, S

Duration: Until dispelled

You halt the normal processes of degradation and wear in a nonmagical clockwork device, making normal maintenance unnecessary and slowing fuel consumption to 1/10th that of normal. For magical devices and constructs, the spell greatly reduces wear.

A magical clockwork device, machine, or creature that normally needs daily maintenance only needs care once per year. If it previously needed monthly maintenance, it now requires attention only once per decade.
