Features [Configurable with a config]

  • Spells can hurt owner feature - Allows spells to hurt the player who casted the spell when enabled, if they used the spell wrong, like summoning a lightning bolt to close to themselves. This feature can help create a higher skill ceiling.
  • Blackholes can become unstable and explode before the spell expires feature - This feature when enabled will cause the black hole to explode randomly around it before the spell expires, causing damage to nearby blocks and players. This feature will also spawn explosion particles inside the blackhole as the spell expires but these particles don't cause damage.
  • Ice block spell can cause ice patches feature - This feature when enabled causes the Ice Block Spell to create ice patches on the ground and in water when the ice smashes into the ground or the surface of water. Ice patches will cause already placed ice to turn into packed ice.
  • Firefly swarm spell will give glowing to targets feature - This feature when enabled will make the fireflies give glowing to anything it hits. This feature paired with the spell can hurt owner feature can make this spell very dangerous if you cast it very close to you.
  • Holy spells will do extra damage to undead mobs - This feature when enabled will make any holy spells that deal damage cause more damage to undead mobs. With Consecration installed, holy spells that deal damage will cause smite weakness on undead mobs.
  • Mana potions rework - This feature allows you to disable Mana potions and replace them with a new item called the Mana Shard, which is a new way to get mana. You can also have Mana potions and the Mana Shards enabled at the same time.
  • Shotgun Creeper spell - This feature when enabled adds a new spell that allows you to fire 3 creeper heads in a shotgun formation.
  • Nucreeper Strike spell - This feature when enabled adds a new spell that allows you to fire a nuclear strike full of creeper heads!

Credits

  1. A special thanks to dreadnews on Discord for the idea to allow owners of spells to take damage. This mod was originally going to be a commission for dreadnews on Discord but I wanted to make the idea configurable and expand on some of the spells so I decided to make it a mod and upload it!
  2. A special thanks to Yirmiri for texturing some of the sprites for this mod!
