Armoured zombie

Armoured zombies are level 85 undead monsters encountered during and after the Defender of Varrock quest. There are three varieties - ones which attack with a scimitar using melee, ones which attack with a battleaxe using melee, and ones that attack with thrownaxes (thereby using Ranged).When one of these zombies is killed, "A strange red mist rises from the dying zombie." This mist must be captured in a bottle (found in the dungeon) to proceed farther within the dungeon during the Defender of Varrock quest. Thereafter, the red mist does not need to be captured.

They are classed as a zombie, therefore giving Slayer experience when killed during a task. Because zombies are undead creatures, a Salve Amulet (e) is very helpful when fighting these creatures, and the Crumble Undead spell works against them, even though melee is strongly recommended.

They are also a good monster to train on as they commonly give 70,000 to 90,000 experience an hour (including Hitpoints experience), even up to 100,000xp/hr depending on stats and boosts.

This is because you can use piety as there is an altar, the Dragon battle axe Special attack with a restore potion (or just using super strength potions) well as a Salve amulet (e). This gives a total bonus of +58% Strength, +40% Attack and +25% Defence
