The special AA ability Enchant Dwerium (x10) can't be learned, and I think its because its listing has a typo. All other enchant {substance name} (x10) alternate abilities are written with an 'x' in the parentheses, While the Dwerium listing is missing the 'x'. Enchant Dwerium (10).
EQ doesn't go off strings. You have the scroll right? Those are not purchased from AA. https://everquest.allakhazam.com/db/item.html?item=71402 Are you scribing the scroll on an enchanter level 61?
Thank you, It has been some time since I've played my Enchanter and I had forgotten how that worked. I crafted the scroll and now have the ability.
