Well, if we're going detailed...
First off, Monks if I'm a general. No way I'm getting anything other than those, because they're too damn effective, healing for a Banded Armor every few seconds 
So, items:
1. Banded Armor/Scaled Helm - Depends if I'm a mana-heavy DG like Sedna, or something that could use more staying power.
2. Scalemail/Banded Armor - Depends what I got in my first purchase, and if I sold it later. In any way, I'll always end up both Scale and Banded.
3. Vlemish Facepalm - By far the best mana item in the entire game. I always buy these if I can, unless I'm playing an ooze UB.
4. Unbreakable Boots - If I went Scaled Helm, I'll sell that to get these. They're nice, HP, HP regen and Mana, what more can a man want?
5. Nimoth Chest Armor - Scalemail and Banded armor wrapped into one, nice. However, if I'm a general, a better Priest is more important than Nimoth.
If the game proceeds into the Filthy Rich zone, where I can buy 4k+ items without sacrificing my Citadel participation, I'll get either the Groffling Warplate or Narmoth's Ring, and it would replace either Banded or Scaled.
