Eleven Limphant Nuts:
Fight a Limphant. When he gives you three Nuts for killing him, keep fighting. Use just one Nut on the next creature you face. You should now have two Nuts. Start fighting Limphants, getting three Nuts when he decides to give them to you -- he will not always reward you with the Nuts. However, you can now collect up to eleven nuts, which is helpful when facing Bosses.
