Anchor

You cause a creature or an object you can see within range to anchored in their position for the duration. Choose a creature . If the target is unwilling, it can make a Constitution saving throw. On a success, the spell has no effect.

If the target is a creature, everything it is wearing and carrying makes them weighed down even more. If they are wearing armor they collapse to the floor and depending on the armor the weight increases.

This is a warlock only spell.
