tModLoader The Thorium Mod

Me(Healer) and my friend(Bard) are having a lot of trouble beating Skeletron Prime on our expert mode world as we are unable to do enough damage to the before morning, does anyone have any advice
You are both playing support classes, so don't expect the best killtimes against bosses. I suggest you to look at our wiki which has progression guides for all classes.

Because any posts you look at since the last time you replied or viewed are considered new.
Also is 1.4.4 port ready?
The OP mentions 1.4.4 port being a thing.

What are those green T items? I got them using a mob and chest loot randomizer mod.
I assume they were replaced with the green T items to prevent other mods using those items' data erroring out in NullPointerExceptions.
I have encountered an error, it seems, because TModLoader has updated:

[23:02:48.876] [.NET ThreadPool Worker/ERROR] [tML]: An error occurred while loading ThoriumMod v1.7.1.2
It has been detected that this mod was built for tModLoader v2023.6.25.31
However, you are using tModLoader v2023.8.3.0
The mod will need to be updated to match the current tModLoader version, or may be incompatible with the version of some of your other mods. Click the 'Open Web Help' button to learn more.
The mod(s) have been automatically disabled.

I'm sure y'all are aware and working on a fix while we speak, but just in case nobody showed you one of these, here it is! Just started getting it today.
