Conjuring Altar

The Conjuring Altar is a block added by Defiled Lands. It can be found inside small structures made of Defiled Stone Bricks and Defiled Sandstone inside all defiled biomes. Breaking it without Silk Touch will only drop Defiled Stone.

A Conjuring Altar will become active under the following conditions:
 * The Altar is placed inside a defiled biome.
 * The 2 blocks above the Altar are air blocks.

If those conditions are fulfilled, the red marks on it will glow brighter and right-clicking it with a Calling Stone will consume the Stone and summon The Destroyer.
