FJumpFallSkillMult

Default: -0.01

After base falling damage is determined (based on several factors, most notably fJumpFallTimeMult), it is affected by the following formula:

final damage = base damage * (fJumpFallSkillBase - (Acrobatics * fJumpFallSkillMult / 100))

Note: as fJumpFallSkillBase defaults to 1.25, the result of this formula with default settings is that damage is multiplied by 1.25 at Acrobatics of 0, and by 1.24 at Acrobatics of 100. It is very likely that the intended result was 0.25 at Acrobatics of 100, which would require a value of -1.0 here (or the removal of the division by 100 from the formula, but that change can't be made by modders).
