You have 900 seconds to do so If not you go into a paralyzing sleep For 1 hour No more and no less.

DMs note: would not recommend to give to a player but would recommend to give to a final boss,
the spell is meant to take 6 minutes to cast or less, 
the object is meant to have reasonable health and also a reasonable Armor class
I would give the object 200-148 hit points and an AC of 16 and that'll be good for a party of three at lv 12
