Boon of Hex Tethering

You have cultivated your Hex Curse to be able to stay at a far range while using it, giving you the following ability:

Your Hexblade's Curse can be used a number of times equal to your charisma modifier, has its range increased to your sight and causes a thin crimson string to appear that tethers them for as long as they're in your line of sight. If a creature moves outside of your line of sight, the curse ends early. This tether cannot be broken or interacted with in any way and, while the tether is active, the tethered creature is considered to be within 10ft of you for the purpose of your spell effects such as Spirit Shroud. The casting range of your spells doesn't change. Your Hexblade's Curse also ignores immunity to curses, a creature can choose to expend a legendary resistance to not have their curse immunity bypassed by you for 3 rounds. This removes any active curses on the target that were caused by you.
