Weapon classes vs Armor classes

Any elemental types will cancel the appropriate elemental types as expected:

• Water kills Fire
• Fire kills Wind
• Wind kills Earth
• Earth kills Water

[edit] is that actually right?

Ethereal armor, say, that's based off of spirit energy or ghosts or something would be quenched by Soulbane or Ghoulbane type weapons

Mercurial armor stops bash attacks, but jabs and pokes go straight through. Kevlar is similar, except that its strengths and weaknesses are based off of the speed of the attack.

Nothing can stop a fairy when it melts down. They're worse than nuclear weapons.
