I have been looking into
Player Death and
Player Flagging.
I have came to conclusion beeing corrupted is a huge burden at the moment. Not only does your death affects you way more than regular player (
which is fine) but it bars you from many activities. Therefore there should be a way to even temporarily hide your corrupted state, for a right price of course.
For example high cost consumable that would hide your corrupted state for up to 2 hours or until you exit node(city) you first walk into.
Another way could be some Epic or Legendary items that could hide your status with active ability.
On the other hand it would be a nice if you could see through disguise somehow. As a priest you could cast "Detect Evil" or something.
