ToME: the Tales of Maj'Eyal

Hi, I want to make an Adventurer that focuses on 1h Channel Staff and Buckler use. What are some talents that directly improve the utility of the 'channel staff' ability, and improve non-strength shield use, beyond those in agility and buckler training? Thanks!

I suspect only Staff Combat and more stat points are going to affect Channel Staff output.
Although Undead Drake: Raze should apply to Channel Staff damage.
Overkill will apply, but only when you kill something, and not with a lot of damage.
Erupting Shadows might be leveraged here.

If you don't mind physically hitting with the Staff, try Weapon Folding.
