how do damage multipliers work?

I ran some more tests:

With wraith Swords each, the ID beat the BL very decisively every time.

With the original equipment configuration of herald lance vs. blood thorn, I moved the ID into the neutral province first, then moved the BL. I did this to force the ID to be the defender always, which worked in getting it to fly over to whack the BL instead of the other way around. The BL won 7 out of 10 battles.

I then tested with a flambeau instead of a herald lance / lucky coin combination. I found that in 7 out of 10 battles the flambeau equipped BL killed the ID in the first successful hit. The BL won all battles, but in two battles the BL was reduced to a handful of HPs. This was mostly because it kept missing the ID while the ID continued to whack it. I should really have restored the luck effect to the BL by replacing the antimagic amulet with a pendant of luck. Then, the BL would have won much more handily.
