Ankh Rune (Unnamed Dungeon Crawler)

The Ankh Rune is a unique item in Unnamed Dungeon Crawler that's found in Tombs or locked Crypt Chests, although they're automatically handed out players at the start of a multiplayer run. In single player, it acts a lot like the Ankh Ring from My Normal Obsession, providing multiple buffs to preserve the player's life. However, if the player still ends up dying, they will be revived with 2 Banished Hearts and 2 empty heart containers, will deal 20% less damage for the rest of the run, consume twice as much Energy, and possess a higher chance of misfiring. They will also permanently lose 1-2 Mana and up to 2 Energy.
In multiplayer runs, the ghosts of dead players can haunt a living player to expend 2 Mana Hearts and 1 Red Heart. To prevent trolling, the best dead player will be revived when a boss is defeated.
=== In-game description (single player) ===
A cast iron ankh capable of reviving the dead... at a price. You become stronger when holding it, but you gain permanent debuffs once resurrected.
=== In-game description (multiplayer) ===
A cast iron ankh that resembles a crucifix. Dead players can haunt a living player's Ankh Rune to revive themselves... assuming the holder has Mana Hearts to spend. Freshly revived players only keep a few of their previous items, and will respawn with downgraded versions of their old weapons. Only two players can be revived per floor.
