After doing many, many runs in the Chaos Plains, I of course was able to keep cutting my time down. Now I'm down to 23 minutes which includes the terrorwebs at the end, which are pathetically easy to lump together if you use the doorway so they all stand on the corner.
But I haven't been using the common aggro route everyone else seems to be using. I always found it a pain in the ass to aggro all 4 groups at the beginning. So I decided to skip the group that is near the end of the run and save them for later. So I would just get the 3 groups at the beginning. Then I would do the normal groups near the shrine, using the shrine itself to lump up the monsters easily.
Then when that area is cleared, I go to the area of the group which I skipped. I aggro all of them and get them lumped up and lay waste. Then kill the 3 that come. Then the second group I bring over to the Dream Rider in the peninsula-ish area and kill them. Then get the 3 mindblades that spawn with the others in the 3rd group.
Then I just aggro everyone else who is left to finish the run, killing the last Mindblade spawn with the Terrorwebs which isn't hard at all to setup, despite the other thread saying so.
That's 23 minutes if done right. It might not be the fastest, but it is extremely smooth and doesn't become frustrating. Keep in mind I'm using an ele primary build with 17 fire magic (golden eggs), but it's basically the same speed in terms of killing since I don't use MoR (the 17 fire magic evens out the damage).
But I've also heard of an 18 minute run where you aggro 5 groups at the beginning. I couldn't find a discussion on optimizing the speed here, so I figured we can do it here. So lets share methods of the fastest runs and aggroing. I can't imagine cutting any time off my method, so I'm interested in what else everyone is doing.
Edit: I actually just did my method in 20 minutes. Odd, seeing how it seems like it should be slower.
