It sounds like the amount you have is about right. The example earlier was a lot of items for that level of party.When I said the "total value of gear and wealth" I meant that to include the magic items.
From what the one guy stated about the amount of magic items their group has, I would say we are well behind that level. I think each character has 1 magic item. I would say they are mostly better than just a +1 item. I think 1 PC has 2 items, but they are pretty niche use. then there are a few scrolls and several healing potions. We've mostly just been going with what is stated within the written adventures we have been using. Maybe we need to bump that up a bit.
A lot can depend on the specific items though. - Are the items that each character have useful for their role in the group? Do the martial types have magical weapons for example?
Just from the ones they get for free, the Wizard should have 16 spells at 6th level in their spellbook, and 10ish prepared. A Sorceror will have 7.It isn't about base combat power with the wizard. It is about the versatility he was expecting as wizard. The group found out an expected opponent was vulnerable to (iirc) electricity. He didn't have any electricity spells. We've had a number of occasions where disguise self or locate object (or some other non-combat utility spell) would have been useful. If he's just going to have the same few spells all the time, he might as well have been a sorcerer and not worry about the book at all.
What sort of spells did the wizard pick and tends to prepare, that they feel that they don't have enough utility?
Remember that if the Wizard has a Ritual spell in their spellbook, they can cast it without needing to prepare it or using a slot by taking the extra time.
