MvPs are free for all, so KS is allowed in ExperienceRO just as it is on most other servers.

DISCLAIMER: Always keep empty space in your inventory at all times, especially when you're about to receive an item, and make sure that you are not overweight. The ExperienceRO team will not be held responsible for any losses due to users' own actions. It is players' responsibility to read the Rules and Regulations and the Warnings.

Cursed MVPs are like the Chapter MVPs except that they are stronger, have twice the drop rates, can drop elemental charm cards, and are only spawned during Black Moon (they are also purple, have a purple aura around them, and are much bigger in size!).

After a summoned MVP is killed, there is a chance that its cursed version will be spawned nearby the kill. When it's about to be summoned, there will be a server-wide announcement saying:

Petra: A new evil plagues the lands!
Each cursed MVP drops Seal of Exorcism. Three seals are the minimum requirement to be submitted to Petra in order to receive a prize.
