Why does it happen that every time I get a rare item and I try to equip it on a character, it becomes cursed...
Uncurse the item 4 times, you'll now have the item selectable as an "Infinite" option in your menu.
After a cursed treasure or Looted treasures are"Infinite" it doesn't seem to spawn cursed any more.
Where this fails however is enemy equipment. If you don't have a full team of say, Expert Maid.
An enemy that equips your person with the Underwear, or Armor will effectively force you to dip into Maid class to unequip them. While you can just stall and let them finish the gear set up, often enough what happens is you get some OTHER dude to replace the gear you wanted gone, leaving the still cursed equipment in your inventory (You can also kinda force this with Latex Rings with some luck)
In previous versions (v2.6-v2.7) you could equip those still cursed equipments on someone who's already reached Lvl 3 of the Cursed Profession to automatically purify it. However in v2.8 it doesn't automatically register you're a lvl 4, and the gear gets stuck at "Reach level 3! 2/3 complete" It DOES correct itself sometimes a few turns in when a battle starts, but I'm still playing around to see if I can figure out a reliable way to trigger the fix
EDIT: Also Vine Bangles are in an odd state. I was curious as to why I nabbed four of them and it didn't go into the Infinite list. Turns out they seem to have a lite-curse effect. No detriment, nothing stopping you from removing them, but a requirement pops up to take 200 Chain ? damage (Its not in the tutorial?) Just wore it and played as normal till it cleared, now working on second
Edit 2: Vine Bangle was a countdown, its a delayed cursed item, turning into Acid Bangle when you use it long enough
