Someone mentioned strikeback influences who starts first, courage...guessing u have amber or Amy...dont know myself maybe increases power

I think it adds power to your character when you are the one attacking first.

What effect does Stop Opp Ability have on leaders? Obviously none on one like Ashigaru but what about ones like Bridget or Morphun? Do you not get your life/pil for that turn? Or similarly for Timber or Van Saar, which if I am correct affect their whole team. With Stop Opp do they just not get their own ability?

And now to really confuse things does a Stop Opp Bonus mean that when you have more than one Leader they also get the ability for one turn...
And... oh no I've gone cross eyed!

None, Leader ability are "outside" of the reach of the any other character,
for now...

For now 00000000000000 lol
