Why do people like to buy Solid Horns?
100 Solid horns can be exchanged at the Exchange Quest for 500 experience. While this is not much at higher levels, you can bring a level 10 player into the Exchange Quest and constantly get around 500 exp for every 100 horns. This is most likely the fastest way to level up at early levels, although it can be quite expensive if you do not gather the horns yourself. Zombie’s Lost Teeth, Jr. Yeti Skins, and Hector Tails are also popular choices, as they provide better rewards than Solid Horns. Though being more expensive, in these cases most people will hunt the items themselves. Zombie Teeth also have a relatively high supply due to the sheer number of players that train on Coolie Zombies for a large number of levels (60-80 for most classes). Again, if you have a main, stronger character, use that to get the solid horns or any other exchange quest items. That way, you get exp for both of your characters.
