Rune Hunting Revised

[Wyrm]

The jungle areas in kurast are good for rune hunting because of the really tight and often large packs of monsters you'll come across in Hell. Just make sure you stay in the area suited to your skills (flayers are cold immune, soul killers are lightning immune, and I think fetishes are fire immune). Unless, of course, you're a hammerdin/skelmancer/windforcer, then you can go through all 3 areas.

I suppose the Cow Level would also be good because of the high density there, but most people are probably sick of that place by now, after several thousand cow runs to get 99 (edit: during .09, that is).
