This made me laugh...

Physical damage (Cutting, Piercing, Blunt)

a. As a general rule, anyone who is naked/half-naked should be resistant to blunt damage, i.e., Pk cannoneer, Dragon Warrior, and Archer, and the hero Otomo. Though the Archer seem to be misleading since anyone with a scrawny body should be vulnerable to blunt.

b. Since the Samurai is the most armored unit in the group, he should be highly resistant to physical damage. However, his armor is partly made of nylon, so it's just so-so on piercing damage. It gets runs too.

c. Besides the Samurai, the only two other resistant to Cutting damage is the Kabuki Warrior, and the Spearman. They had the same nylon clothes. Or used ones by retired Samurais.

d. The poor Pk Cannoneer is the most vulnerable to cutting. This is easy to remember, as anyone knows butter/lard can be sliced easily with a knife. Especially a hot one.

d. The only non-hero unit that has good resistance to Piercing is the Chemist. Thanks to his diet of prunes and regular skin dehydration (doesn't do too well on his complexion and body form though). Though many say that is not the case. Arah and Otomo are the only other people who share the same passion for prunes. Though Arah should be naturally resistant to piercing as she likes to use those pointy things to puncture others as well. Oh wait, i think she just knows how to get out of harms way, that's all.

e. The Chemist is most vulnerable to blunt. Anyone with that frame could have his bones broken easily. Or it's just because of his osteoperosis. So i think in general, anyone who's thin and slim are vulnerable to blunt (Arah is one). WITH THE EXCEPTION of Kazan. That tub of lard is an abnormality in all of Battle Realms. Ofcourse Lotus Warriors are an abnormality, but that is out of their own decision.

f. Just think of Kazan as vulnerable to hammer and nails (blunt and piercing).

Special Damage (Explosive, Magical, Fire)

a. Almost everybody is resistant to Fire, except ofcourse, the Samurai, and the heroes, Arah, Garrin, and Otomo. I think they called each other up in the morning and decided to wear something water resistant to, y'know, be ready for any rainy day. And yes, what could be more water resistant, than well, something flammable! What a concept!

b. Garrin and the Samurai share the same strength and weaknesses on Physical damage and Special damage respectively. With Garrin coming in as the poorer of the two on taking Special damage.

c. Those resistant to Explosive damage are the Kabuki Warrior, the Chemist, and the heroes Arah and Kazan. The KW (with his, that thing he plays with his hands) and the Chemist (with his weasel rockets) are naturally attuned to pyrotechnics so no question about that. Arah's resistance to explosive thingies dates back to her childhood. so don't ask me why.

d. Kazan is naturally attuned to Fire, so remember that he is both resistant to Fire and Exlosive.

e. The Chemist is the opposite of the Samurai when speaking of Physical and Special damage resistances.

f. Again, nudity brings the benefit of being resistant to Magic damage besides Blunt damage. So count the Dragon Warrior, Pk Cannoneer, and the Archer in, and ofcourse, the hero Otomo.

Teeheee...funny. :D Thanks for letting me post Kuentin.
