Buy weapons like sword, elemental magic staff, gun, missile launcher, or other available weapons, recruit more ally and set their strategy, and/or upgrade your stuffs to help you to fight your enemies, but make sure you have the money for those things, while also save some money (if you wanted to) so that you'll get money bonus based on interest rates after the next battle is
