Akarat's Champion damage bonus

Hey, if my bracers improve my physical damage, should I use the Embodiment of power rune? Will all my attacks be improved, or do those style damage bonuses only effect direct damage abilities?

It will affect all attack skills with the physical rune element. However, the difference will be negligible (not noticeable) with all but the skill with the most damage boost (legendary items and 6piece set bonuses).

Is Akarat’s Champion an Attack skill?
