Values by rank

Mortal Blow scales with Attack. Its value at each rank is 16.1 + 4.6 × rank:

Rank	1	2	3	4	5	6	7	8	9	10
Value	20.7	25.3	29.9	34.5	39.1	43.7	48.3	52.9	57.5	62.1

The value is the game's internal number for this skill.

in combat = round(value × skill power × max(0.35, hero damage ÷ 600))
hero damage = Attack + all elemental damage
skill power = 1 + 1% per point in the other Execution skills + 2% per rank of each skill that boosts it

The damage factor has a minimum of 0.35 and no maximum. A hero with 600 damage and no line mastery or synergies gets the listed value; how it becomes damage or healing per hit depends on the skill's type and timing.
