/In short, if the dog is in the line of fire, I suggest it moves back a little (just a bit) so that Ivor can't shoot it. But this is only for one or two turns; then Mahus should arrive, maybe even Erephir... Anyway, Nightmare will have to take the hit: it has the highest chance of dodging and a lot of HP, but even if it doesn't dodge, together with Mahus, they should take down Ivor, and Erephir might help too.
That's what I think./
