Tether Control

As an action a tether can be used to make a ranged spell attack. A hempen rope can be used to do 1d4 bludgeoning damage within a 30ft cube. If a metal chain is used the attack does 1d6 bludgeoning damage but the range of the attack is halved.

At higher levels the spell's damage increases by a damage die of the tether used in the attack. One more damage die at 5th level (2d4/2d6), 11th level (3d4/3d6) and 17th level (4d4/ 4d6)

As an action this spell can be used to animate and take precise control of tethers in the spell area to tie knots and weave a number of times faster than normal equal to the ability modifier used for these skills (Int or Wis) as long as the caster is proficient with that skill. Taking precise control of tethers can also be used to exert fine control over objects as long as they are no more than 10 pounds. Taking precise control of a tether for more than one round to do complex actions or tie/ weave something causes the spell to require concentration. ** If using the tethers to control a weapon the weapon must have the light property.

Creatures attempting to pull on the tethers must do so with a strength check vs your spell save DC.

In combat up to 50ft of only two tethers can be controlled at once, the tethers can be used in the following ways. 

• You instantaneously use a bonus action to hitch the rope to an object or willing creature.
• You instantaneously use a bonus action to send a lasso to grapple a creature that is large or smaller using the casters spell attack modifier. The caster's knot tying skill is used in the grapple check. If the caster wants to grapple using both animated tethers at once they can use an action to roll the check at advantage if both tethers are used against one creature or disadvantage if the tethers target different creatures. Roll both dice for each opponent and use the lowest for each.
• You instantaneously use a bonus action to untwine the threads of a up to two tethers.
• You instantaneously use an action to splice two ropes together or to create a prusik loop on the end of a rope.
• An action can be used to attempt to restrain a grappled creature using your knot tying skill verses their strength or dexterity check.

Creatures being grappled or restrained must succeed on a dexterity check vs the caster's spell save DC.
