While using overlord with the lithium mod the armor values on the skeletons are reduced for example, if you give a full diamond armor to a skeleton, he will only have 3 armor value, meanwhile, without lithium it's 20, which is normal.

Just take a random set of armor and equip it on a skeleton and use some kind of health indicator or something of the sort and you will notice they will have a lower armor value then normal.

What version of Lithium did you test this with?

version of lithium used: lithium-fabric-mc1.18.1-0.7.8.jar

Thanks! It may be a bit before I can get to it, but there is something you can do in the meantime that should fix it for you and speed up a fix.

In the Lithium config, you can try overriding various options as false one by one until it starts working correctly again. Once you find which it is, let me know and I can get Overlord to make that one false by default.

I would try mixin.entity.data_tracker.use_arrays first. If that doesn't do it, you can start by disabling a whole category at a time (mixin.entity, mixin.math, etc) to find the category then check specific settings in that category.

Im kind of new to this stuff, but I will try to fix it, if im able to fix it I will post a new comment, thanks for the reply and the suggestion.

After a while I found out the problem is in "mixin.entity", when turned to false the values work as intended, but when I tried to find the specific subcategory causing this problem the values would always remain incorrect. I tried to change 1 by 1 the values of each variable, but it just doesn't work and I have no idea why, for now the only solution I can come up with is turning "mixin.entity" in the lithium config to "mixin.entity=false"

Hmm. I wonder if it's some combination of the entity settings then, or something that can't currently be overridden individually

Okay, looking at Lithium, there may be a few more optimizations that aren't documented.
Try mixin.entity.skip_equipment_change_check=false

yah, that solved the problem, thanks!

I'm going to leave this open until I fix it from Overlord's side
