Need Help! what is 1.0 damage coefficient?
Coefficients are scalar multipliers. Meaning whatever stat is in consideration gets multiplied by that number, and that is its value for the skill in question.
For example, if a skill has a .4 healing coefficient, it gets additional healing added to its base according to 40% of your healing power.
So a 1.0 damage coefficient means all your power gets added.
