A couple months ago Thomas over at Original Edition Fantasy posted Aaron Allston's extended stat chart from Wrath of the Immortals.
I'm normally not that interested in the whacked out high end of D&D, preferring to whack out on the lower levels. So I might have seen this chart before and not paid any attention to it whatsoever.
I think this chart cought my eye this time because I've been seriously considering making a high level killer dungeon, something in the Tomb of Horrors genre but with a higher monster:trap ratio. This is one of those "well, I've never done that before, I wonder if I can?" sort of ideas I get sometimes. I wouldn't actually use the chart above, it's just thinking this idea has me surveying the field of crazy high level D&D.
If I did make such a dungeon, it wouldn't be suitable for a Fight On! article or lulu publication, since I would totally be using material from Arduin and other ridiculous high level sources. So it would be a free PDF and maybe some outlaw ashcans.
