With an arcane, gather up mobs, web them up, crushing despair > circle of death > fod, finger/pwk survivors, if there are any after the finger/pwk, just move on, rinse/repeat. Von 1/4 are a peach for that, Chrono as well (just hold and dot/polar ray the orange name, be sure to pwk the acolyte as soon as it goes active). Works in fens as well.
It can be done in wizking as well, but it's much more of a pain there because activating the whole room brings up DA, and with all the casters active and spamming cometfall getting harried is a bad thing. Best thing there is juts to pull the mobs to the right shrine, jump up on the sarcophagi and ice storm/firewall, and pick off 1 by 1 with finger.
Von5 is kinda annoying without at least some spec in fire, webbing and icestorming the zombies is much slower kill/minute than other vons where you can instakill.
Von1 - only buff you need is displace and whichever one of exp retreat/haste, run to the minotaurs, crushing despair, circle, wail, run down to the 3 hobgoblins, cd/circle/wail, run all the way to the kobold, web the room, activate trolls, wait for the ogres, cd/circle/wail, rinse/repeat will probably be needed as ogres and trolls have decent saves. After that, run to the fork, round up mobs, cd/circle/wail. Run to the troll boss, cd/circle/wail. Ddoor and recall after that, ignore red names.
Von4 - displace, fom, cold/elec/fire resist, jump, invisi. Invisi, run to the lever, pull, run inside. If the earth ele is bothering you, pwk. Run in, jump on the speaking head, talk to it, round up the mobs (grab the two wf to the left, but don't go past the line where shadow meets the light), cd/circle/wail. Run to the right side, watch out for fall-out floors, when you see a group of warforged cd/circle/wail. Ignore the dogs for now. Keep running till you get to the last door, blow it open, gather up mobs, cd/circle/wail, web if there's survivors, rinse/repeat. If any dogs followed you, web/ice storm them. If you're not a PM, watch out for disco balls. Once everything is dead, invisi, hug the left wall, pull the lever, go inside and shrine, recall.
Chrono - fire cold elec resist, displace, dw. Run inside, start it up, dancing ball in the middle (just cast one so the mobs are rounded up better, best location comes with practice) to the left. On the right side from where you enter, there are 3 mobs - melee, acolyte and caster (close to far side). Web the caster, stand next to the acolyte. As soon as it's active, pwk the acolyte, finger the webbed caster. Hop over to the danced mobs, cd/pwk/wail, rinse repeat. Ignore orange name till everything is dead, then energy drain, cd, hold, nuke. Through the portal, shrine, recall. You can cheese it by going up the ramp and picking off mobs from there before they're active, but its just slower and there's no real reason to do it.
In edq1 just seal farm, and kill the mobs in the pit when getting scorpion chest (they actually have saves there, so you might need to ice storm them).
You get the idea - round up, dc/circle/wail. If there's a mob that casts deathward, instakill asap before it fires it off. With a divine, it's just a lot of running around in circles while BBing, while keeping divine punishment stacked on the orange names and imploding/destructing mobs that refuse to be bb kited.
Do NOT use any spells/gear that can blind mobs or invisi you, you want the mobs aggroed on you and following you as close as possible, on an arcane or divine. Biggest problem is generally getting stunned or danced (hello lich form).
Btw if you have a pimped up divine, just BB farm amrath quests for large mats instead, it's much less braindamaging and about as profitable, if not more (or maybe I'm just unlucky with scrolls
).
