I will try to make this as short as possible.
I considered the following prices:
Cultish Masque 25k / Gold 2.5m / Gold Ticket 7.5m
After you added Cultish Masques trade and nerfed the drop rate we obtain: 7.5k for each anubis. This requiring to walk through 4 levels of a dungeon and surviving there. Also it required a mid-geared char. Respawn rate is 15.
Now you added Nose Rings trade at 100%. With this drop rate we obtain: 12.5k for each minorous. We don’t have to walk a lot of maps for it (only 2) and those monsters are easy as fuck. Also respawn rate is 60.
Why is each Nose Ring 12.5k? because you need 2 times the amount of cultish masques for the same reward.
How much zeny do we farm in gonryun? 2k
So right now the economy is fucked up.
How to fix this? Increase prices ONLY FOR NOSE RINGS (on npcs) as soon as possible.
This mistake was huuuuuuuge. But you can fix this if you work fast.
