Fixed Duration (Power-Ups 4) is a +0% feature, making any successful Affliction last exactly three minutes.
Reduced Duration 1/3 (Power-Ups 8) is a -10% limitation, reducing it to one minute.
Cyclic, 1 minute, resistible is a +20% enhancement per cycle. In theory, such an ability has an unlimited number of cycles, but this is obviously unfair, since the odds of getting any use out of later cycles is extremely low.
A more reasonable approach would seem to be reducing the value of each cycle by a certain amount each time. You could just say half the value of cyclic each time, but that might be too generous. Maybe apply the value of Resistible (or a flat -30% for abilities which allow a resistance roll through other means, like Affliction) in a cumulative fashion? The first scheme gives cycle value * (0.5+0.25+0.125...) which approaches base cycle value at infinite cycles. The second (assuming -30% per cycle) gives cycle value * (0.7+0.49+0.343...) which approaches base cycle value * 2.333... at infinite cycles.
(My math is pretty shaky; you may want to check these numbers)
So, I believe that a fair value of 'infinite but resistible cycles' is somewhere from the basic cost of one cycle to a bit over twice that. For a 1 minute cycle, that would be 40% to ~94%.
Add the reduced duration for the original attack, and you get +30% to +84%. Cosmic, adding utility, +50%, lies in that range and is the general-purpose 'change the rules but in a somewhat balanced way' enhancement.
Therefore, I would recommend a +50% enhancement for Affliction to work as you suggest.
