5th-level Spell: Life Support

High Magic (Necromancy)

When a creature you can see within range is reduced to 0 hit points, you can sacrifice your own vitality to bolster its life force. For the duration, the target can continue acting while at 0 hit points and does not fall unconscious. Any damage it takes is transferred to you. If the target is healed above 0 hit points, the spell ends.
