Over the course of a minute it's about 360 or so potency. Impact means that for a minimum of 50% of the fight you get the extra 30 potency and 1 additional mana for each element (to a total of 8 mana generated vs the 9 from stone/fire). Meaning it's your damage insurance in the case that you're unlucky, reducing RDMs dependence on RNG up to that point. It's fine, doesn't need to be changed.
