Sympathetic Link
4th-level enchantment (Bard, Sorcerer, Warlock, Wizard)
Casting Time: 1 action
Range: 60 feet
Components: V, S
Duration: Concentration, up to 1 minute
A creature you can see within range must make a Wisdom saving throw, with Disadvantage if you are within 5 feet of each other. If the creature fails, the creature is magically linked to you for the duration, as long as it can see you. The creature feels your pain. When damage is dealt to you, half of the same damage is dealt to the creature. However, when you are healed, the creature is also healed by half of that amount.
If you are reduced to 0 hit points while the spell is still in effect, the affected creature must succeed on a Constitution saving throw or be stunned for 1 round.
Whenever you take damage the creature suffers the effects of the spell before you make your concentration checks.
At Higher Levels. If you cast this spell using a spell slot of 5th level or higher, you gain Advantage on your concentration checks to maintain the spell. If you use a spell slot of 7th level or higher, the duration is 1 minute and doesn't require concentration.
