For more astral for Yomi with CBM I really like a Lord of Plenty. Here's a sample build I tested out:
Lord of Plenty (Body 1339, 150 hits)
Magic: Earth 4 Astral 4
Dominion 6
Scales: Order 3 Productivity 2 Heat 3 Growth 3 Misfortune 2 Magic 1
Awake
He gets 2E2S a month! Insanity.
You can hire a ton of Bandit archers for E2 Sorcerers to buff up, they do some good damage with their arrows and swords, and LoS reduces the damage they take. Flaming arrows is Enchant-5 in CBM, but when you hit it, it's another boost in power.
