The nether swarm event is a boss fight where the source of the swarm will spawn Ghasts, Wither Skeletons, and Magma Cubes! Made for Forge 1.12.2. 

How to spawn the swarm -

You first have to defeat the wither. The wither will give you the nether star. You also have to kill blazes to get blaze rods and blaze powder. Next you have to craft the nether heart. The nether heart recipe is shown in the pictures. Then you can summon the Nether Swarm by right clicking the Nether Heart.

Defeating the swarm -

The source has about 650hp. He does not fall or get knocked back. He also does not attack. Only the mobs. Which makes it easy to kill. The hard part is what he spawns. To defeat this you have to be decked with my recommended gear. 

  • Enchanted Diamond Sword and Bow
  • Full set of Enchanted Diamond Armor
  • 10 - 15 Enchanted Golden Apples

When you have finished -

When you have finished the swarm, A crate will spawn full of goodies. What is in hear is a swarm gem, the trophy, 9 fire Charges, 4 blaze rods, and 4 blaze powder. 

Fire Staff and Fire Charge Cannon -

When you craft your swarm gem in your inventory or a crafting table, It will make about 20 Nether Bars. You can use this to make the fire staff and fire charge cannon. The fire staff deals 13 damage and sets your enemies on fire. It also lasts a really good amount of time! The fire charge cannon does not last very long, although its a one kill weapon for most mobs. To use this, You need at least 1 fire charge and you use it like a bow. Crafting recipes for these in the pictures.

Enjoy the mod!
