For whatever reason, in the afternoon he takes off the headband. Does he immediately 'forget' one spell? On the one hand, he only has the capacity for 8 spells now. On the other hand, maybe your int score only matters while you are doing the actual preparing.   I think I would say he forgets a spell, his choice.

#7 RCanine Aug 17, 2014 23:01:16	If the headband was forcibly removed, it might be more fun to determine the lost spell at random; if the wizard intentionally removes it, I'd probably be ok with him selecting the spell to forget.   However, I wouldn't let him forget a spell he had already cast that day if he had spells left that he had not cast.
#8 Mephi1234 Aug 18, 2014 6:20:41	I would also allow him to remember the one he forgot when he put the headband back on.

In the meantime, for Rulings purposes, there're two factors that enter here: Simplicity, and Preventing Abuse.   Simplicity favors the notion that you just let the player keep all their prepared spells until the end of the day.   Preventing Abuse favors the notion that certain item limitations are there for a reason, and you shouldn't be able to get around them.   I'd say this:    If you just take off the hat, and you're not out to get any sort of incidental benefit that you couldn't get if you continued to wear it, then, fair play, just keep 'em all. Too much un-fun effort to figure out how you lose them, whether you regain them, etc.   If you, however, put on a different magic hat, or dis-attune yourself from the Headband to free up an attunement slot, or otherwise try to gain a magic-item-related benefit you couldn't get while wearing it -- OR -- if you give the hat to someone in an effort for two of you to 'share' its powers -- that might qualify as abuse. In this case, I'd say you lose any benefit you got from the hat, and those prepared spells you lost do not come back until/unless you re-prepare spells, with the hat on again, after a long rest.
