Value17.621.525.429.333.237.14144.948.852.7

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 Artillery 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.
