About this Mod

I WONT MAKE A 1.20 PORT!!

A medium sized addon for the popular mod Iron’s Spells ‘n Spellbooks that brings a ton of new content mainly focused on the new spell school,Necro,focused on debuffs, damage over time and curses

Discover new enemys armed with their own magic, inspired by Minecraft Dungeons and other kinds of fantasy meadia like Skyrim and Terraria/Calamity

Aiming into adding a ton of exploration content and expand the normal proggresion of Irons Spells with new armor Tiers:

Arch:Focused on spell builds with only a kind of spell, offering unique skills to those schools of magic

Hybrid:Focused on combined builds between two "compatible" schools, offering less buffs to spells but alowing more versatility

This addon is still in active development and is VERY likely to get content reworked,removed or added from update to update

The mod currently includes

  • +12 new sets of armor with their own spell stats
  • +90 new spells scattered throuh the spell schools
  • +30 new weapons each with its own unique skills and tats
  • +5 new Ores to upgrade the normal ISS gear
