Old Armor Class is no longer used to determine hit chance. Instead:

  • 1 AC = 1% damage reduction (rounded down).
  • AC is split into:
    • Physical AC: Protects against conventional physical force and weapon damage.
      • Blunt: Reduces damage from crushing force and impacts.
      • Slash: Reduces damage from cutting, tearing, and wide-edged attacks.
      • Pierce: Reduces damage from focused penetration and thrusting attacks.
    • Elemental AC
      • Fire: Reduces damage from heat, combustion, plasma, and burning effects.
      • Ice: Reduces damage from frost, freezing temperatures, and cryogenic effects.
      • Lightning: Reduces damage from electricity and electromagnetic discharge.
      • Force: Reduces damage from compressed air, kinetic pressure and invisible impact.
      • Necrotic: Reduces damage from decay, entropy, soul erosion and corruption.
      • Gas: Reduces damage caused by toxic fumes, corrosive chemicals and acids.
      • Holy: Reduces damage caused by radiant, purifying, or divine energies.
      • Blood: Reduces damage caused by manipulation of blood and flesh.

Example:
If a target has 20 Slash AC, incoming slash damage is reduced by 20%.

Damage is reduced after all other modifiers (crits, posture effects, etc.).
