Thorium Mod

Description


Welcome to the Thorium Mod! The Thorium Mod is a "Vanilla+" content pack that adds a massive variety of new items, weapons, armors, NPCs, bosses, and even 3 new classes into the vast world of Terraria!

With magnificent sprites from BrutalLama, AdipemDragon, Barometz, BluNinja, and many others, as well as crisp code from direwolf420 and DarkLight, we hope everyone enjoys the Thorium Mod as much as—if not more than—the base game!

Current Version: 1.7.2.5
  • Port to 1.4.4 versions of Terraria + tModLoader!
  • Additions and changes to the mod in the scope of the Labor of Love update!
  • Many item changes, balancing, and bug fixes!

ℹ️ Make sure you're on the stable version of 1.4.4 or on the 1.4.3-legacy version. It won't work on the preview version!

ℹ️ Having issues installing Thorium, or encountering bugs when playing? Be sure to read the Technical FAQ & Known Issues thread!

Full changelog: https://thoriummod.wiki.gg/wiki/1.7.2.5


  • 2,700+ new items
  • 3 new classes: the Thrower, Healer, and Bard
  • 2 new biomes: the Aquatic Depths, and natural Graveyard
  • 11 new bosses and 3 new mini-bosses
  • 10 new Town NPCs


The Thrower class expands on the now-removed damage type from vanilla Terraria, transforming it into a full-fledged class based around high damage and high mobility.

After setting a Technique with a Technique Scroll and building up enough Technique Points, activate your Technique for a special offensive, defense, or mobility-based ability! Stay on your feet, and don't exhaust yourself!


The Healer, a special multiplayer-focused class, supports allies with gear that can heal and buff, whilst still being able to dish out damage when in a pickle.


The Bard delivers a show with various instruments as weapons that both deal powerful burst damage, as well as granting various buffs to nearby allies.

@Derpy_Penguin: Not until tml 1.4.5 is released or close to release, which it isn't at the moment

Is Thorium currently planned to be updated for 1.4.5 compatibility? If so, is there a working timeline for about when it may be finished?

@Adrian Jade: As long as the boss hasn't been defeated, it should keep spawning the mirror. You can doublecheck by installing a mod like boss checklist to make sure it's not checked.

Illusionist bug: if you die or run from the fight / do not defeat him, there is no way of resummoning it. The confused zombie will NOT sell the spawn item and the mirror will NOT spawn in the dungeon anymore, which is a flawed / unfinished boss mechanic.

@Vlidmir Putan: Thank you for the reply and for explicitly allowing the translation!
I also appreciate the clarification about some text not being included in the localization files yet, and I’m glad to hear that you’re already working on it.
Thanks again for all your work on this mod!

@kanban: Yes, you are granted permission to translate the mod. We are aware of some texts not being in the localization files and are actively working on this, but it will take some time, like until the end of this year.

Hi, I really enjoy your mod and I’m interested in translating it into Japanese.
Would it be okay for me to make a Japanese translation for this mod?
I don’t have much experience creating tModLoader mods myself, so I’m planning to use a mod called “External Localizer” which extracts localization text into an HJSON file and allows it to be translated externally.
I’d also like to ask whether all of the mod’s text is included in the HJSON localization files. In the extracted file I currently have, it looks like some NPC dialogue may not be included, so I wanted to check whether those lines are localizable through HJSON, or if they are handled in another way.
