Right now if you want to have many items and you only have one this is how you make more:
Save, then go to a character and remove the item you want to make more of, then save again. After that, load the character you unequipped the accesory/weapon/armour you removed will be back on him/her and you will have an extra one in your inventory.
After Alex becomes a Dragonmaster, go to Lann and speak with the mayor. He'll ask if you want to celebrate... say that you do. After the celebration, speak with him again for the Devil Tear.
Train Alex up to level 18 and he will learn the attack: 'flash'. Change your tactics to Alex uses flash and everyone else defend. Use this in a battle and any normal battle will win instantly. If not, then your party is too weak and you need to train up.
