Arcanists and their spells

[Wolfandre]

Actually, it's mentioned in the blm and whm quests and lore that they are unique for using the aether of the land (hence the destruction wrought by the war of the magi.) So, by exclusion, we can see arcanists use their own aether.

Yes, but I had said Thaumaturge and Conjurer, not Black Mage and White Mage. Granted, conjurers don't traditionally use personal aether, but it is shown that it is possible through the conjurer quest line.

That is actually a bit out of context, given the subject of arcanist spells. Arcanists use their spells to manipulate the aether in their targets bodies to enfeeble and enhance.

However, given how vague her wording is, one could argue that she meant it either way. *shrug*
