The game features a Weapon Synthesis system which can be used to create powerful and effective weapons.
All weapons gain EXP from battles until they reach a level where they are "Maxed" and can be synthesized along with another similar weapon to create an even stronger one. This is accomplished by the use of Toady . Toady can also analyze weapons and make suggestions for combinations, and will helpfully warn if a combination he's attempting to digest will give useless or negative results. He can only combine two weapons of the same kind.
