TEXT: 1
  These corrections and emendations have been made in the
  BASIC ROLEPLAYING hardcover edition and are summarized
  here.
  SKILLS (p. 46-84): p. 58 - First Aid.
  “FAILURE” condition should read: Attempted treatments have no
  effect. The patient's condition does not change, and no further
  First Aid attempts may be made.
  “SYSTEM NOTES” first sentence should read: Each application of
  First Aid applies to a single wound: once a First Aid attempt has
  been made on a given injury, whether successful or not, addition-
  al First Aid attempts on that injury have no effect. 
  POWERS (p. 85-168): p. 94 - Magic Spells -
  "Blast"
  Sentence 3 should read: Under most circumstances, armor (non-
  magical) will absorb the damage, and the Blast spell can be
  dodged. To clarify, normal armor and the Countermagic spell work
  against Blast; Protection and Resistance do not.
  COMBAT (p. 187-210): p. 191 et al -
  Clarification of Parrying Procedure
  This section is to clarify how the BRP parrying procedure works in
  a different manner from the parrying procedure in 2nd and 3rd
  editions of the RuneQuest game. The new BRP parrying procedure
  is derived from the Stormbringer 5th edition rules.
  A successful parry, whether with weapon or shield, deflects ALL
  damage from the incoming weapon; you don't roll damage and
  compare to the parrying weapon’s HP, with the excess “getting
  through”.  A Parry is an all-or-nothing affair.
  Shield AP/HP are only used when dealing with damage done
  directly to the shield itself, as in an attack to try and destroy a
  shield or parrying weapon (p206); or when resisting Damage vs
  Shield AP on the resistance table when parrying a Crushing blow
  (p196), or when 2 or 4 HP of damage are done to the “parrying
  weapon or shield” on the Attack and Defense Matrix (p193).
  p. 193 - Attack and Defense Matrix
  Definition of the term “FULL DAMAGE”. The term “full damage”
  crops up several times in the Attack & Defense Matrix. Precisely,
  it refers to “the damage which that type of attack would normal-
  ly do”. It is not the same as “maximum damage”: a Greatsword
  “full damage” would be 2D8 on a normal success, 2D8 bleeding
  damage on a special success, and 16 damage ignoring armor on a
  critical success. Damage bonus in all cases is rolled and added
  afterwards.
  Asterisked Section at bottom of page should read: If the parrying
  weapon or shield is destroyed during the parry attempt, roll the
  attacking weapon's normal damage and subtract the points of
  damage used in destroying the parrying weapon or shield. The
  remainder is damage which penetrates the parry attempt to dam-
  age the defender (armor still protects). If the attacking weapon is
  destroyed during a successful attack, damage is still inflicted on
  the defender but the weapon is broken at that moment.
  SPOT RULE: Extended Range (p. 223)
  This Spot Rule is deprecated. Instead, use the Missile Weapon
  Range Modifiers on p257, as follows:“At the weapon’s basic range,
  the skill chance is unmodified. At medium range (double the
  basic range), the chance becomes Difficult, and at long range
  (four times basic range) it becomes ¼ the normal skill chance.”
  The Point Blank Range Spot Rule on p229 still applies: where range
  is less than DEX/3 in meters, attacks are Easy.
  SPOT RULE: Volley Fire (p. 235)
  Clarification: The volley fire rules apply specifically to
  thrown/self-propelled weapons. These are almost always utilized
  at the rate of 1 attack per combat round, with the RoF used for
  volley fire. The Difficult modifier applies here.
  p. 381 - Attack and Defense Matrix
  Asterisked Section at bottom of page should read: If the parrying
  weapon or shield is destroyed during the parry attempt, roll the
  attacking weapon's normal damage and subtract the points of
  damage used in destroying the parrying weapon or shield. The
  remainder is damage which penetrates the parry attempt to dam-
  age the defender (armor still protects). If the attacking weapon is
  destroyed during a successful attack, damage is still inflicted on
  the defender but the weapon is broken at that moment.
