4th-level evocation
Casting Time: 1 action
Range: 30 feet
Components: V, S, M (a thread or string weaved between fingers)
Duration: Concentration, up to 1 minute
Choose a target in range. That target becomes the center of this spell effect. You then choose another target of the same type within 30 feet of the first to link. Once targets are linked, anything that occurs to the first is shared with the linked target.
If the first target takes damage, the linked target takes an identical amount of damage not effected by vulnerabilities, resistances, or immunities. If the first target is given a condition, the linked target is automatically affected by that condition until it ends for the first target or this spell ends. If the first target drops to 0 hit points, the linked target must make a Constitution saving throw or also drop to 0 hit points.
At Higher Levels You can link an additional target to the first for each level of the spell slot used above 4th.
