Weapons are classified by the type of damage they deal:

• B – Bludgeoning
• P – Piercing
• S – Slashing

Some monsters may be resistant or immune to certain types of damage.

Weapons may deal multiple damage types:

• If a weapon deals two types of damage, all damage is treated as being of both types.
  • Example: A weapon that deals B/S damage is considered fully bludgeoning and slashing — not half of each.
  • A creature must be immune to both types to ignore the damage completely.

• Some weapons can deal either of two types of damage.
  • In such cases, the wielder may choose which type to deal when it matters.
