Duwell's Objective Dwelling

Select a flat surface within range with a vacancy large enough to accommodate the object you've chosen to be the material component of this spell. The chosen surface must be inanimate, if it is animated at any time throughout the duration of this spell the spell ends immediately. The spell also ends if the chosen surface is moved more than 100 ft. from its position at the time of the spell's casting. As you cast this spell you remain within range of both the object and the surface to which you mean to bind it. When you finish casting the spell a pair of identical magical symbols appear on both the object and the surface to which it is bound, henceforth referred to as its "Objective Dwelling." When you finish casting this spell you specify a condition that will cause the object to return to its Objective Dwelling. When triggered no matter how far the object is from its Objective Dwelling it will attempt to return to its Objective Dwelling, flying at a speed of 60 ft. at the end of every round in its direction, weaving through corridors and turning around corners if it must, taking the fastest possible route to its Objective Dwelling. While moving toward its Objective Dwelling the object will not move through any object or surface even if it is fragile or penetrable such as glass windows or falling water. If the object is barred from reaching its Objective Dwelling by any means it will move as close as it possibly can to its Objective Dwelling before ending the spell on itself and falling to the ground. 

If a creature is holding the object when its condition is triggered they can make a Strength (Athletics) check against your Spell Save DC as a reaction, ending the spell's effect on the object and its Objective Dwelling upon a success. Additionally, if a creature moves within 5 ft. of the object while it is in the process of returning to its Objective Dwelling they can make a Strength (Athletics) check against your Spell Save DC as an action, ending the spell's effect on the object and its Objective Dwelling upon a success.

Dispel Magic or a similar effect successfully applied to either the object or its Objective Dwelling will end this spell's effect.
