When rolling to wound, a Slayer's Strength, including any modifiers for weapon (eg, a Great Axe), is increased until it is equal to the Toughness of his opponent, up to a maximum of Strength 6. If the opponent's Toughness is lower than the Slayer's Strength, including any modifiers for weapons, the Slayer does not receive any Strength bonus. For example, a Slayer armed with a Great Axe (S5) is fighting a Dragon (T6): normally he needs a 5+ to wound, but because of the Slayer skill his Strength is increased to 6 and he therefore wounds on a 4+. Note that the Armour save modifier is calculated at the modified Strength score, in this case it is -3 for a Strength 6 hit. If the Slayer were fighting a weedy Goblin (T3), he would use his normal Strength of 5 and would therefore wound the Goblin on a 2+, with an armour save modifier of -2.
