So the issue is basically that it scales with hit points. I'll make it more like Healing Light and similar effects so that it doesn't scale with maxlife.
Induced Phenomena has a heal in it and I plan to keep that effect in some form. I'm thinking something like this, and forgive me for the rough brainstorming, didn't sleep well last night and a lot of this comes from those hours of laying awake
Cosmic Cycle
While expanding increases your temporal resist penetration by X%. While contracting increases your Willpower for Paradox by X%. (Basically Paradox Mastery but in a more interesting form).
Polarity Shift
Shifts the Polarity of your Cosmic Cycle. If it starts expanding it fires temporal bolts at targets within range. If it begins contracting (not sure, could put a heal here but it's already on Reverse Causality, of course Reverse Causality could be changed).
Some talent name here
Creatures in your contracting Cosmic Cycle have their three highest stats reduced by X. Creatures in your expanding Cosmic Cycle have an X% chance each turn to be blinded, pinned, or confused (this is an age manipulation effect as that's something thematically I've kinda brushed off this go).
Reverse Causality
Creatures leaving your contracting Cosmic Cycle heal you by X. Creatures entering your expanding Cosmic Cycle grant you X% of a turn.
