Zombies are level 6 undead creatures that are quite strong, and appear 'yellow' in Tracking for Rangers. They have the ability to Curse you when they attack, so they are a bigger threat to magic-using classes.
Known Loot: Edit
In dungeons and Cemeteries.
It is a good idea to carry a Ring of Remove Curse with you when you are fighting Zombies, especially if you are a magic-user.
