Eldritch Thirst

A crimson, spectral tether connects you with a creature within range, then forcefully draws its lifeforce into you. Make a ranged spell attack against the target. On a hit, the target takes 1d6 necrotic damage and you recover hit points equal to the damage done.

The spell creates more than one tether when you reach higher levels: two tethers at 5th level, three tethers at 11th level, and four tethers at 17th level. You can direct the tethers at the same target or at different ones. Make a separate attack roll for each tether.
