and magic items boosting your stats to 18, etc. Just like the ogre item...it's hard to keep myself from using it, and hard to not consider it when creating a character with point buy. I mean, why put points into something if you know you're going to be able too boost it 10 minutes from now?
I don't think it's good item design when they override your ability scores and make them irrelevant. Sure, you can argue that you still have to make the choice to wear such an item and not something else, but I still think your ability scores should always matter. Only min-maxing comes out of items completely overriding ability scores, knowing you can always buff an 8 to 18. Headband of Intellect would be much better granting +2 to Int and would also benefit Wizards as such.
