While that is the second best alternative since a constant 20% less damage is really, really nice... why not just keep rerolling the Friend List until you find a 100% one? Either for a couple of Seeds or 8 AP, you can reroll one Friend and all non-friends from the list. Chances are you'll save more than time than you lose this way.And how are you going to get this 100 Ascension outside of Light Grids? Multiple Defender/Ascension weapons from the Ori Shop? There are far better uses for Ori, you know.
In all honesty, I don't think you have ANY idea what you're talking about.
