Burning in Mules

You can also have a character do an "impossible" run to Charsi, which will have the same general effect. If you stand between the stash and the little stone wall between it and Charsi so that you're close enough to the corner so you can still highlight Charsi when she goes into her hut (and stands next to the forge) but not in the actual corner. When you click on Charsi to run over to her you'll be caught in an endless run, running into the corner. That will keep the game active as long as you want/need, but you should either turn off the monitor or alt+tab out of Diablo 2 because the screen jitter will hurt your eyes after a while (starts giving me a headache after 5-10 seconds).

Found that on the Amazon Basin a while back, used it several times. The only slightly annoying part of it is that Charsi never seems to go under her shack when you want her to and it takes a little while to get into position so you can target her and not wind up going around the wall instead of into it.

Oddly enough you can do the same thing in Act 5 with Larzuk, if you stand in the right spot between him and the 2 stairways leading to his platform, but that's a lot harder to get to work and isn't very useful for breaking in characters, since chances are, to get a char to that point you've already played them longer than 2 hours (unless they were rushed).
