Zelda II: The Adventure of Link/Items

Enemy Drops
Enemy drops are provided for every sixth enemy kill. Instead of earning the usual experience point amount for the sixth consecutive enemy kill that you perform, a potion or point bag will fall to the ground for link to collect. Link must duck down and stab these items with his sword in order to collect them.

Quest Items
In order to obtain help from certain townsfolk, Link must perform quests that will aid them before they will return the favor and be of aid to him.
