Out of curiousity, what effect does beguile have on a character, if that character is by themselves? I was shooting the Black Widow with Lady Irane's cheap bow, when the Black Widow advanced towards me slowly and stopped within striking distance to cast beguile on me.
First off the description for beguile talkes only about melee attacks attacking someone randomly 50% of the time. I have a bow (no melee). Secondly, if I attack randomly somebody else 50% of the time and I'm by myself. I can only attack the Black Widow and so the spell has no effect.
I recommend that the Black Widow stop casting beguile vs. 1 unit (unless it does have an effect that I'm missing). Secondly the Black Widow shouldn't cast beguile vs. an Archer Unit.
