The easiest fix would be to include a "how many do you want to buy/make?" Question to Malady's conversation before she chooses your items and gives you your reward and exp. She will need to check Maplestory 2 Mesos for sale that you have sufficient stuff, which you have sufficient space in your inventory for the rewards, before she performs the transaction.

The cooler fix is to alter Malady to utilize the crafting system, very similar to Beefy's Kitchen. Give her a Sack (shop NPC for buying things with Dark Tokens) and also a Cauldron (crafting NPC for cooking items based on her own recipes), and the built-in functionality of these kinds of NPCs will care for the amount issue. The only tricky bit is that a few of her items could be crafted two different manners. I am not sure if the crafting system may manage two recipes which yield the exact same item. Also, using this system won't give exp (but may provide Diligence exp).Reboot Update Preview

The brand-new Reboot world is becoming added Maple M Mesos to MapleStory! Within this world, creatures are more powerful and give more EXP. As you fight, you are going to receive significantly more mesos, as well as equipment relevant to your character's job. Useful items are made to be accessible through gameplay, so some items will not be available from the Money Shop, or may only be sold for mesos instead. Item enhancement is simplified, and trades are handicapped. Rather than purchasing what you need from other players or the Cash Shop, you will earn it naturally through gameplay since you collect items and grow more powerful!
