You know I went through the game without ever crafting a scroll. In fact the only one's I ever used was the Rain at the very beginning and resurrection a few times. I never sold any and had my mage NPC carrying them all ... just because. Other than resurrection they seem kind of pointless.
Is there ever a Resurrection spell you can learn or is it scrolls only?
I see your mage just met Cassandra?
I also was not really into the crafting & blacksmithing. I mean, I took them to level 5 (+2 base, +1 talent, +2 gear) to play around with them. I also used the Rubies to take my resistances to 100% and Tenebrium & wetstone to boast my weapons. Other than that, I never bothered with crafting.
At some point in my playthrough I did find a spellbook for Resurrection, but with playing 2 LW, it is (imo) pointless to learn.
You are correct, I just met Cassandra and killed Ahru for the achievement before I left for holiday. After I come back from holiday I will continue playing and preform the other achievement that is associated with Cassandra.
