Nightmare zone question?

saw something on youtube which have 2 people do nightmare zone in a team, with one of the accounts being a boost account; having 5 quests done so it's easy for the other account to just train there with melee pray on and get good exp.

Was wondering if anyone knows if this has been patched or still works? Thanks

 

It still works and the other guy doesn't even have to stay in with you, there's people who offer this 'service' at the nmz area in world 1 for about 20k a go

 

Thanks buddy!
