Agents question

[Lamias]

Playing still 0.96 Edit: I also use Yarkis' DeI - Agents Balance Submod


My spy has: Authority 2, Cunning 5, Zeal 4. He also has the furtiveness skill (Rank 2), which gives him +16% that the poison assassination will be successful.


The enemy general has: Authority 6, Cunning 4, Zeal 6. He also has (in commander effects) 14% + 13% chance to wound enemy agents in self defense.


So the question is this: How on earth, when i try to assassinate this general, the poison attempt gives me 10% to succeed, whereas the concealed blade gives me 16%?

I think this makes absolutely no sense.

Thoughts? (My household and traits are irrelevant)
