Observed behaviour

• Server crashes when entering the nether from overworld with irons_spellbooks:amethyst_resonance_charm
• Same behaviour applies on irons_spellbooks:conjurers_talisman

Modpack: Direwolf20 S14 1.14.2 (Minecraft v1.21.1)

In Direwolf20 there is irons-spells-n-spellbooks version 3.12.1 but I also tried the same with upgrading the version to 3.14.4 and encountered the same issue

It also doesnt matter if I just have the item in my inventory or equipped in the curios inventory

Expected behaviour

I expect to enter the nether normally without a server crash

Steps to reproduce

1. Install Direwolf20 S14 1.14.2
2. Start a Direwolf20 S14 1.14.2 Server
3. Build a Netherportal and get the following items: (you also get the issue when you only have one of them)

• irons_spellbooks:conjurers_talisman
• irons_spellbooks:amethyst_resonance_charm

4. Enter the Nether

Server Type

Dedicated Server
