Felling (X) reduces the target's Unnatural Toughness modifier by a number equal to (X) before determining the Damage caused by a weapon.
Felling does not reduce Unnatural Toughness by (X) when calculating Toughness Bonus as it is applied to True Grit.
First Damage calculation, then applicable Talent mitigation; the Felling Quality has no affect on True Grit.
True Grit (pg 152):
The character is able to shrug off wounds that would kill lesser men.
Whenever the character suffers Critical Damage (after Armour and Toughness), reduce the amount by his Toughness Bonus (to a minimum of 1).
I am not interested in debating the definition of "lesser men".
I am making a reasonable assumption that when this rule refers to the reduction of Critical Damage due to "Toughness" it means Toughness Bonus. Otherwise, reducing Critical Damage by 40+ points makes True Grit redundant.
I am making a reasonable assumption, based on the rules, adding Unnatural Toughness modifers to TB effectively increases the total TB.
A wounded Ork Meganob (TB 4, Unnatural Toughness +5, Personal AP 14, 7 Wounds remaining, has True Grit) is lumbering through a ruined building (Cover AP 10), and "Lucky" Eddie decides to sneak into Short Range and take a shot with his "trusty" Meltagun. Eddie is lucky; he successfully sneaks into range and hits the Meganob. The Pen of the Meltagun is doubled at Short Range (12x2=24), so the Meganob's combined AP is negated. Eddie rolls an 8 and a 9 for Damage, adding 10, for a total Damage of 27. Subtracting the Meganob's combined TB (9), it suffers 18 Wounds, resulting in a -11 Critical Injury (off the Table), but this is reduced by a combined TB of 9 due to True Grit, meaning the Meganob only suffers a -2 Critical Injury.
So, my questions to the forum are as follows:
A- Is this a correct assessment of Felling?
B- Is the final Critical Injury a result of correctly applying the benefit of True Grit?
