Get gems Frostwall link it with increased duration for longer effect and get lighting warp. Now when you for example open a chest and chaos orb drops which does not belong to you immidiatly start casting Frostwalls around the orb so any other players cant get to it before the ownership lock expires. When it does pick up chaos orb.
It is pretty easy with a bit leveled Frostwall and duration.
The worst thing you can expect is getting kicked from group and get some harsh blame.
