Uber tether

A magical tether of thirty feet in length is magically made between you and your target. your target is healed 1d4+2 (+1d4 for each additional spell level) per turn.

if the spell lasts three rounds of combat your target is "Charged" and looks as if they are made of crystal with yellow glowing eyes. they gain damage resistance to all damage and advantage to attacks for one round (+1 round per 2 additional spell levels) during this time they cannot be affected by healing spells

if the target goes more than 30 feet away the spell ends not including charge
