User:Aeldrion/Projects/CVM/Nether cores module

The Nether Cores module adds Nether Cores.

A Nether Core is an item that can be used to transform blocks in an area into nether blocks.

Obtaining
Nether cores are obtained by standing on a Sacrifice Altar for six seconds.

Sacrifice Altar
A sacrifice altar is a manufactured structure made of a small obsidian pyramid with fire on top. Standing on it will disable a player's Regeneration and Fire Resistance effects, therefore the player will take damage when standing on the Sacrifice Altar. Every six seconds, the player will be rewarded with a Nether Core.

Using
When placed on the ground, the Nether Core will spawn a dying Blaze and turn nearby blocks in a 15*15*15 area around it into Nether blocks and replace some nearby mobs by Nether mobs.

Mobs
When a Nether Core is placed, nearby mobs may be replaced by other Nether mobs.

Other nearby mobs will be set on fire.
