Magnet Trap

Spell Lists: Artificer
Level 2 Transmutation
Casting Time: Action
Range: 30 ft.
Components: V, S, M (an iron rod wrapped in copper wire)
Duration: Concentration, up to 1 minute

You create a powerful magnet which appears at a point you can see within range, which attracts metal in a 10-foot radius Sphere for the duration. Tiny metal objects that aren’t being worn or carried in the area fly toward its center.

When a creature enters the area of attraction for the first time on a turn or starts its turn there, it must make a Strength saving throw. On a failure, it has Disadvantage on attacks made with metal weapons until the start of its next turn.

Also on a failure, a creature that is made of metal or is wearing metal armor cannot move away from the center of the area until the start of its next turn. On a success, it still must use twice as much movement to move away while within the area of attraction.

Using a Higher-Level Spell Slot: The radius of the Emanation increases by 5 feet for each slot level above 2.
