How to raise NPC Wisdom?

[475513a]

Outside of editing their stats directly?

High wis is essential for lategame wish casting, and vanilla had potions to raise wisdom. Is there a solution with IR, e.g. to raise Aerie's from 16 to 18?

In non-Revised IR, I think the only items that grant wisdom are Axe of Hrothgar, Silver Ioun Stone, and the Tome of Understanding. In revised IR, it's instead Jerrod's Mace that has the wisdom bonus instead of Axe of Hrothgar, while the rest are the same with an addition of the Amulet of the Seldarine granting +1 wisdom. Another user just complained that there were no intelligence-raising potions anymore, too - starting to make me think that there should maybe be a potion that gives like +2 to both somewhere.

You could also give her the point from Lum's Machine, right?
