Once afflicted with "Cursed Week," Possession Armor takes constant zero damage (or occasionally 0.1 damage).
I explored the entire map (everywhere accessible), but found no mechanism to resolve the issue.
Perhaps the biggest problem with this game is the lack of any way for the player to actively figure out the solution to the situation.
Possessed Armours like to sometimes parry your attacks which causes them to do 0 damage.
However I don't see how you're only doing 0.5 damage per hit. Even an early game Primitive Spear is enough to defeat it. Possessed enemies are usually focused on cursing you, which gives you quite a bit of leeway to do damage.
What race and Race level are you?
However, this phenomenon is actually occurring in my save data. If this is unintended behavior, should I provide screenshots and the save data?
For reference, the maximum damage I dealt was 4.3 using the "Blunt Axe."
However, I cannot deal this amount of damage consistently; most hits result in a "miss," 0 (likely a parry, though it happens very frequently), or damage of less than 1.
The "Miss" is actually just you missing the Attack. Every weapon has an accuracy statistic that you can see next to the damage range (It's right above "Speed"). The "Blunt Axe" has an accuracy of 80%, so there's a higher chance for you to miss with that one.
I've also checked the damage and your output is more or less the expected result for this weapon. The "Blunt Axe" just doesn't output enough damage against a Possessed Armour.
Check my other comment for some suggestions on what you could do. You should also check the User Manual for crafting recipes.
