Rebirth Monuments are statues in Elden Ring that give the player the ability to summon Spirit Ashes in the area. They are represented in the world by obelisk-shaped monuments and on the HUD as a spectral archway on the left edge of the screen.
Spirit Ashes can only be present in the area surrounding a Rebirth Monument. If you move near the edge of the rebirth area, your summons' health bars will start to flicker, and if you leave it entirely the spirits you summoned will vanish.
Not all areas that allow Spirit Ashes to be summoned have a physical monument present, including many boss chambers. The most reliable way to tell if you can summon spirits is to look for the archway icon. In some cases, areas that allowed summoning when a boss was present will no longer allow it once the boss has been defeated.
Where to find Rebirth Monuments in Elden Ring
Rebirth Monuments can be found all across the game, including most boss chambers, legacy dungeons, self-contained combat areas, and scattered throughout the open world.
