How do you make "Seduction" effective?

[hoo]

Ah...So I wasn't just imagining things when I saw that seduction is pretty ineffective.

But otoh, doesn't this mean that Arco/BL has assassins? Who really cares if you FAIL the seduction attempt when you can kill the commanders? Maybe it's a two for one deal with a slight (say 5%) chance of seduction but then you get the assassination attempt with some pretty good mages.

but glad to know, that I'm not missing out on anything.
