Aether barrier should be moved from AMs to the crafter guild, probably to under enchantment. It's so similar to runes and install lock and vaporize metal in that it's just anotehr castle improvement/defense.

Elemental mist (does what vaporize metal does) might as well be removed.

Bless weapon and armour might stay with the Rislans. they are religious things and should be cleric, not crafter.

Bags of holding I have no real opinion on one way or the other.

Thieves getting dispel magic is a bit problematic. I'm not sure I'm in favour of everybody being able to get dispel. Maybe make it not crafter and give it as a spell to a few more guilds besides Arch-mages. It would make sense for elementalists and necromancers, so you have the pick of more than one guild as a looting partner (before it was enchanter or AM, now it might just be AM unless more guilds get it).
