Just noticed that the Fool just has a normal treasure listing. Should we specify "including possessions listed below" I guess?
Any ideas on possessions for the epic one? No particularly great ideas here. Any high-powered staff that's great for evokers?
What equipment budget are we talking about here?
That's an excellent question. I can't seem to locate an epic NPC wealth chart. A 20th-level NPC has 220,000 gp in gear, and this fella's 21st-level, so a bit higher. Factor in the fact that it's CR 24, and has double items, I could see a budget of at least 500,000 gp. I'd probably go closer to 750,000 gp.
It looks like we're OK with the staff...
From page 209 of the DMG:
21st 975,000 gp
22nd 1,200,000 gp
23rd 1,500,000 gp
24th 1,800,000 gp
Doubling 21st gives us 1,950,000 gp
Doubling 24th gives us 3,600,000 gp
Even without doubling, it still leaves some wiggle room.
