Viktor's Soul Link (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Duration:||Concentration, up to 1 minute|
Make a melee spell attack against a creature within your reach. On a hit, you intertwine the essence of you and the creature. Any damage taken by you is taken by the creature and any damage taken by the creature is taken by you. The transfer of damage in this way does not provoke a concentration check. Other effects (i.e. status effects/instant death) do not transfer.
While your essence is intertwined with the target of this spell, you use your action to siphon the creature's essence. The creature must make a Constitution saving throw or take 1d12 necrotic damage. Instead of taking the damage, you gain hit points equal to half the damage dealt, rounded up.
If you and the target creature move more than 60ft apart, the link is severed.
