If you get below 40k exp, or anywhere near that at armoured zombies, your tactics in killing them fail... Heavily. TBH, if you're not just pulling numbers out of your rear like most do, you were probably doing several things wrong. Read up on one of the two guides found in general guides. Chuz suggest a familiar that can attack, but from what I make of it he was refering to armoured zombie, I believe? If he was, dont bring attack summons to armoured zombies because they're in single combat. Definitely bring one to zombie monkies though. I haven't had melee stats in the 70's for quite awhile now, but I guess you might be able to get 60k/hr using piety there, counting exp given to all attack, strength and defence. Don't take my word on that though. I'd stick with armoured zombie unless you're very rich TBH, by the time I use 2 super sets there I often can rack up 150k+ worth of loot. Then I must be thinking about something wrong. The armoured zombies come from the Defender of Varrock quest right?
