They replace the master hit with the notions of good attack (the attacker makes a throw equal to or less than the good attack score, as shown on a table in relation to her attack score) and good parry (five points less than the parry score with the d20 in dice notation). A good attack not parried by a good parry implies a serious (or critical) impact (throw 1d20 and read the result on a table). When the attack or parry-test die shows 20, this can lead to a fumble. The extended rules also allow dodging thrown weapons, introduce specific rules for empty-hand and horseback fighting and infection (fever) for wounds.
