Iron's spell book mob attribute addon
Java mod listed for Minecraft 1.20. Downloads from the MC Java Mods app on Android.
⬇ Download on CurseForgeThe author built this one for Minecraft 1.20.1 on Forge. On other versions it may install and then do nothing.
There are many schools of spells in iron's spells 'n spellbooks. (fire, ice, nature, etc.)
However, most mobs are not separately weak to fire or resistant to ice, and by default undead are weak to Holy and resistant to Blood, and fire-resistant mobs are resistant to the fire school, but the schools have little significance. This add-on adds one resistance and one vulnerable school to many mod bosses. For example, Ender Dragon is vulnerable to ice and resistant to the End school.
