Nature's Curse

You touch a manufactured item. Unoccupied items automatically fail this Wisdom saving throw. For the duration of this spell, the item is reclaimed by nature. Metal rusts, edges blunt, and wood begins to grow branches and leaves. Using weapons affected by this curse grant disadvantage on attack rolls and deal half damage. Armor and shields contribute half their normal armor class bonuses, rounded down. Tools only allow you to add half of your proficiency bonus, and checks with it are made with disadvantage. The GM may rule other effects apply as well.

Dispel magic has no effect on this spell, but remove curse or other similar abilities can remove it.
