On Deadliest Warrior, they had a show of French Musketeers vs. Ming Empire warriors. The Ming had a very interesting weapon called the Nest of Bees.
The Nob is 32 rocket-powered arrows in a wooden basket. Uncap the end, light the fuse, aim, and wait. Suddenly 32 arrows going 220 mph are heading downrange.
They aimed this thing at mannequins representing about twenty soldiers with one officer on a horse mannequiin front and center. Six of them were hit, with three of them being kill shots. The targets are unarmored, and the penetration is good. The officer in the center is not even touched.
The speed of the arrows is about twice that of a hand-drawn bow.
I consider that making the effect of this something like a grenade with a great deal of range. I'm going to suggest Fatal damage.
===================
Sun Tzu vs. Vlad Impaler
I liked Sun Tzu's trick of soaking the bushes of an approach to his line with sesame oil, and then shooting a flaming arrow into the bushes to light the area on fire.
One point the show made was that with the flaming wad of stuff on the arrow was that it limited the penetration on the target.
I'd drop the damage level on an ordinary arrow by one. I'd probably call the fire Damaging per each turn, and some sort of chance to beat the fire down one or two levels depending on effort and skill, and a chance for the fire to rise in damage to Dangerous and to top out at Fatal.
=====================
One thing I don't like about Deadliest Warrior is that sometimes they match up a barbarian vs. a soldier one on one. The Romans knew, I think??, that one on one, the Celt could clobber them. That's not the point.
With a disciplined force, the soldiers would have won the case study of Roman Centurion vs. Rajput (who was reminiscent of the wild ways of the barbarians). Or like the recent fight of Sun Tzu vs. Vlad the Impaler. I thought Sun Tzu was an actual accomplished general and not just a philosopher. But it is indeed possible that Vlad one on one would have killed Sun Tzu. That's not really the point again.
Its a bit annoying.
