Minecraft curse of disappearing?

I caught a bow with the curse of disappearing, but what does he do?

Cursed objects are not dropped at death like other objects, so you can pick them up again, but just disappear

In itself it is not necessarily bad. As long as you do not die while wearing it, everything is fine.

Advantageous is the enchantment zbsp in PvP on servers if you do not want to have a separate extra inventory for the arena and the opponent should not be able to collect the armor and weapons… Then just make the curse on the kit and good is xD

Achso the PvP answer was naturally from the point of view of a server admins / Owners meant xD
