Like I said, I'll chip in for the scroll, but Ark's illiterate, so someone else is going to have to read it...
Anyways, I've never been that good at choosing items, especially for something like this. I like rods of rope and adamantium saws (just cuz), but what are some other things that would be useful?

It's mr. Bunko's Emporium, it has loads of useful stuff.
Ring of Sustenance or Everlasting Rations are always nice.
So is the Fortifying Bedroll, and the Haversack. Also the Survival Pouch is very useful if you don't have a caster that can be your swiss army knife.
Tooth of Savnok is HUGE if you are wearing heavy armour, giving you no reduction to speed at all is kindda nice.
Also, Candle of Invocation is a VERY powerful item, summoning something as stupid as a Solar and actually commanding it is quite nice for 8400, it can cast true ressurection, or revivify + revenance combo, or just win any combat you want it to.
The Decanter of endless water also have endless uses, so does the immovable rod.
That's the Items I know that almost everyone can use, Oh and don't forget the 11 foot pole.
