You must disable Hard Monster Staff.
Because this item useless now.

People making PK for get this item because it gives to us 4000 np point. it is like gift for Pk!

Yesterday i was reads about new system

Hard Monster Staffs useless now this isnt good for cz.

good luck with new system.

we can kill a boss in Hard Monster area in 40-45 second.
maybe we can get 1K nps.

Have a Fun.

NP should come from pk and not from farm

This is what we focus on with the latest changes.
We removed the "leech KC blessings" and added NP/max point bonus for pk kills
We added a new pk quest - kill 300 = 5KC

Hard/Easy Monster Zones are actuallly like a Bonus, where people can farm some Gold and good Jewels, but it should not be a main source of NP.
4000NP in 15min was just to much - if you compare it to pk.

Beside that we had many problems with "restore my 4k NP voucher, cause I DC " requests.

Hard Monster Zone NP drop:
I tested it and I did kill about 30 Monsters in 15min
With the 15% drop rate for a voucher, this is = 4 or 5 vouchers in 15min.

Ofc it depends on your luck - as always with drops.

So you can get approximately 2250 NP from 1 run in Hard Monster Zone.

I might even increase the droprate a little, if more people think, that it is to low.

Dont forget that you can drop:
CSW+1, FN+1, Medal of Puzzle, ROV, Medal of BDW, Valkyrie etc... from Hard Monster Zone
