Shadow Altar is a boss altar found in Shadowlord Platforms within Abyss. It is used to spawn Shadowlord.


One Shadow Altar spawns in each Shadowlord Platform.


Spawning Shadowlord[]

When interacted with while holding a Book of Shadows, the Shadow Altar will consume it and spawn Shadowlord after a delay.

The delay is dependent on the amount of active Bloodstone Lamps nearby, with the first lamp taking one second to turn off, and subsequent lamps taking two seconds to turn off. After all lamps are turned off, Shadowlord will spawn after an additional two seconds. Five seconds after spawning Shadowlord, the four lamps that generate with the platform will turn back on.

By default this leaves a nine second delay when spawning Shadowlord; however, breaking the lamps will decrease the time, and additional powered lamps of any type in the area will add to the delay.

Torches can be used as a substitute for lamps, however they will simply drop as items as a replacement for the lamps turning off, and will not be replaced after Shadowlord spawns.

If this is done with the Night Vision effect active and a Blank Realmstone in the inventory, the Blank Realmstone will be converted into a Dustopia Realmstone.
