Does this allow players to essentially bypass any/all undead encounters ever?

This seems really funny and oh so very wrong at the same time

This belt has a large silver buckle, usually depicting the image of a tiger.

The belt grants the wearer an enhancement bonus to Dexterity of +2, +4, or +6. Treat this as a temporary ability bonus for the first 24 hours the belt is worn

Do items like this grant a permanent ability score bonus after 24 hours, so is it possible for a single person to buy one +6 after pooling money, then share it with his party? Does this also allow people to purchase every belt and wear them in turn for 24 hours to gain a permanent +6 to every stat? Also, if the bonus is permanent, is it an untyped bonus, and thus stacks with other bonuses such as the Ioun stones?

Where is the list of replacement feats that each class can choose if they have a banned feat.(ex. Wizard who gets a bonus feat at lv5)
Is it only selectable from spell mastery, metamagic, and arcane discovery, or are there different options like how Wizards gain spell focus for scribe scroll?
