Destroy

For whatever item the Player chooses, the player must roll a percentile die to determine the level of destruction dealt with the item. This can either render an object destroyed, unusable, or the item can still be used but with major difficulty*

-On a roll of 0% to 33% the item is considered 'Damaged'. This minorly increases the DC of any ability checks or usages with the item [A damaged thieves tools kit would result in a higher DC when lockpicking]

-On a roll of 34% to 66% the item is considered 'Unuseable'. This negates proficiency and makes all rolls with the item at a disadvantage and at a higher DC [An unusable weapon will not allow a proficiency bonus, and an attack roll with the weapon equipped  will be at disadvantage]

-On a roll of 67% to 100% the item is considered 'Destroyed'. The item crumbles, melts, or decays in whatever manner is appropriate for its makeup. The item can not be used at all after this effect takes place.

When considering magical items [EX: Wand of Fireballs] if the percentage rolled for the Destroy spell is between 0% to 66%, the item will backfire. The user of the item must make a saving throw concerning the damage dealt by the item [EX: Dex save for a lightning-based weapon]
