Chest Item List

Now consider this event:
Every box takes around 7.5mil mesos out of the system (assuming that people use the MTS to obtain their NX.) Once opened, it releases usually a scroll or an item that can be scrolled. This increases the supply of the preexisting items, which means lower prices for EVERYONE. Then... with the chaos scrolls and the various other scrolls, which WILL most likely be used, even more mesos taken out of the system. For every PAC broken, mesos taken out of the system. For every balanced fury made, extreme amounts of mesos taken out of the system. (Like, a NL will buy it and hang onto it for life...)

Unless there's some NPC you can buy 60% GFA for 7.5mil from, it is not taking mesos out of the system.

It is bringing more items in, but it is not taking mesos out. The only time mesos are destroyed are when people buy things from NPCS or lose them to taxes. MTS does neither of these. It does take NX out of the system.

I make ~200k mesos/hr, 7.5mil over the duration of the event might be possible (depends how long it runs) but I'm not gonna count on it. Not everyone has an Arch Mage to sell leech for 5mil per hour when they need mesos.
