Arachnid Anchor

Choose two points within range. These two points become tethered together for the spells duration. If one or more points are an unwilling creature, they must succeed a Dexterity saving throw or become tethered. Tethered points cannot move further from each other than they were upon the casting of this spell. A creature can attempt to drag the object/creature it is tethered to (following standard push/drag/lifting rules). 

If a creature would fall further than the tether would allow them too, they are instead suspended in the air at the extend of the tether and do not take any fall damage.

The tether can be broken via forced movement out of the tether's range or as an action if the creature succeeds a Strength saving throw. The tether has 10 AC, HP equal to 1 + your spell casting ability modifier (minimum 1), is vulnerable to slashing, acid and fire damage and is immune to poison and psychic damage.

This spell’s range increases by 30ft when you reach 5th level (60ft), 11th level (90ft), and 17th level (120ft).
