Any wondrous item with a wizard spell and CL of
<6, or any with a clerical spell and CL of
<10. No armor, weapons, rings, rods, staffs or wands. No potions. I would rather stay away from single use items as they are a waste of the magical essence imparted to them.
Magic Item Compendium has lots of good, cheap stuff.
If I may offer some suggestions:
- Healing Belt (spend 1-3 charges to heal 2d8, 3d8 or 4d8 hp, 3 charges/day)
- Amulet of Tears (spend 1-3 charges to get +12, 18 or 24 temp hp, 3 charges/day)
- Gloves of Fortunate Striking (reroll an attack roll 1/day)
- Circlet of persuasion (+3 Cha skill checks)
Should be able to make anything on that list for 2000 gc or less (circlet might be a little more).
We can go over the details via personal message.
