It's basically gauntlets of ogre power, for intelligence. Those gauntlets (or even better) are common to most D&D games, and most folks plan for them at least to some extent - one or another strength challenged characters will eventually use them - it's one way to make a dual class character more effective, or ensure your heavy armor, high wisdom cleric can eventually hold his/her own in melee combat as well ( see Viconia or halfling fighter Mazzy in BG 2).
I expect that when a full version of BG3 is released, there will be the usual panoply of stat 18 items - .
I'm more bothered by the itemization of weapons and armor thus far. Other than the standard +1/+2 gear, most everything else has a fairly severe downside - as if all magic carries a curse these days. I presume that might be the explained as an effect of the warping and twisting of magic in recent Faerun history, but I do not recall any such overarching effect being claimed to date in current game lore and material. Examples of "flametongue" or "envenomed" weapon equivalents should still exist - hopefully such normal items without negative characteristics will come later.
