Bishop's Twilight Cure

Upon casting this spell on a willing target, they become wrapped in shadows, gaining the following benefits:

• They restore 2d4 hit points when they deal damage for the first time on their turn. If they would heal to full health or are already at full health, then the healing is negated.
• When they reduce a creature to 0 hit points, they gain an extra attack which stacks with specific class extra attacks, and they regain half their lost movement speed.
• If they fall to 0 HP while under this effect, they immediately teleport 15 feet in a random direction and make their first death saving throw with advantage.
