The guide was done on SP. I got Vizharan in regular area. I played melee necro on MP last ladder too. Wasn't satisfied of drops so I had to trade for it. Vizharan usually costs 5-10 tg, but it's a pretty common item to drop, so I'm sure some people will take sigents/other items for it. Fauztinville is much harder than Duncraig because thee are ranged monsters (Harpylisks) that always run after you as you don't use Lightning Arena, for example. Thus, they should be the first ones to kill together with Necrobots.
Destruction Baal needs patience. Usually, all wdm-based charms defeat him after some time, because of not being able to one-shot the boss like casters. Inti RW for The Way of the Phoenix is the cheapest weapon against this mofo.
