Diamond arrows/bolts from Mo in NLC are the best option currently outside of Von Leon quivers (better than the showa arrows since these ones stack to 5000 instead of 4000) but buying them is a pain. The NPC requires too much clicking. You can only buy one set at a time. Each set you want to buy requires you to: 1. Click to confirm you want to buy something. 2. Try to scroll down using that janky scrollbar. 3. Click the arrows/bolts. 4. Click yes. 5. Click to close window. This may seem like a minor inconvenience, but when you're buying about 20 sets in a row and have to do this 1-2 times per week, it can get very tedious. I'm suggesting either: 1. Move the arrows and bolts to the top of the list so we don't have to scroll down. Besides maybe ACPs, these are probably the only things people commonly buy from this guy anyways. 2. Remove that unnecessary first page of dialogue if possible, so that it jumps straight to the list of items for sale (assuming you've completed to the quest for it). Or alternatively: Make it work like the Showa NPC where we can just enter the amount we want one time and be done with it.
We will increase the amount of arrows/bolts that can be bought at once in a future update. Since it is kind of a low priority change i can't tell when our developer will be able to get to it. Thanks for your feedback!
