My current plan involves taking advantage of the crumbling cave. It's high DL enough to do some very interesting things.
As a caster, you maybe able to kill a couple things (say an ancient red/white dragon if you have the matching bolt) that give mountains of XPs and gain a bunch of levels that way. If you're lucky enough to run across some chaos knights/warriors, you can get some eternium gear. If you roll-scum a character with a scroll of familiar summoning, you can get companion like a greater moloch, emperor lich, or great wyrm. Emperor lich is very nice, since you can get him to summon, then kill all of the summons with him, in hopes of getting some easy high DL loot. A named wyrm (preferably not karmic since they don't regenerate) or greater moloch can clear Darkforge for you if you're careful/lucky, so you can get the SoRS and the other items there, plus maybe sip the pools for hopes of TCtrl or a wish. If you get a fire immune companion, then immediate ToEF run is also an option from this point since pretty much any fire immune monster except a greater fire elemental can kill the ACW easily.
Hoping to win with every class, doomed. Archer, Barbarian, Bard, Beastfighter, Druid, Elementalist, Farmer, Fighter, Monk, and ULE Priest down.
