Benedict's cross should be +1 complexity, rather than power, and he should have one more potion slot. Katash's potion slots can only be used for channeling (Spirit) effects, so he might be more effective if those slots were used for enchanted items/focus items instead, because he can get more uses out of those without losing very much versatility that the potions would give. Also, he should have one more focus item slot (which could translate into two more enchanted items slots/potion slots). Everything else looks fine.
