DND/Combat/Armor Class.md

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
    • Blunt, Slash, Pierce
  • Elemental AC
    • Fire, Ice, Lightning, Force, Necrotic, Gas, Holy, B

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.).
