Martyr's Chalice

The Martyr's Chalice is a craftable Hardmode Healer spell that kills the user immediately upon use, but in the process heals all allies in the world. When the user dies, a spiral of glowing blue particle effects spreads outward from the player's location. After being healed, all allies will gain invulnerability for 3 seconds.

Like all healing items, it benefits from any additional healing effects and cannot receive a Modifier.
