The Headband of intellect used to set int to 18. It was nerfed to 17 because people whined that in EA it used to make raising int irrelevant for a mage… which is in fact a stupid argument, since you don’t want to go all the way to the endgame with a low int Wizard only because you had what’s broadly considered a crutch-item in the beginning.
And head slots arre not “extremely valuable “ at all. It takes a whole lot before you start to see items of some significance there. I had my barbarian sitting on a “+3 m movement” until Act 3 or so, because there weren’t really that many better options.
To this day I still have half of my party wearing borderline pointless stuff in that slot just to not have it unused.
But that’s beside the point. It doesn’t change the fact that popping almost 400 gold PER-character on a daily basis only to get a +1 in their main attribute is absolutely NOT what I’d describe as cheap or money-effective.
Especially since ALL THAT AMAZING GOLD your party saved doesn’t even cover for a fraction of the ACTUAL good shit for sale by the time the player hits Act 3.
