Aversion Obelisk

The Aversion Obelisk is a block added by Ender IO. It is used to selectively prevent mobs from spawning around it.

Usage
The Aversion Obelisk requires filled Soul Vials and Micro Infinity to operate.

Each Soul Vial added to the machine will prevent the type of mob stored inside the Soul Vial from spawning around the obelisk. For example, if the player adds a Soul Vial containing an Enderman to the Obelisk's inventory, it will prevent Endermen from spawning within its area of effect while powered. The Aversion Obelisk can store up to 12 different Soul Vials.

The Obelisk's area of effect is a square area centered on the block. Its radius, as well as the machine's power usage, depend on the installed capacitor: The device does not require more power when more Soul Vials are added.
