What is the enhancement in mind? How should it look and feel?

Now clue how it should be done visually

Please provide any additional information below.

Eclipse gains:
SS Always 15 to the said you are moving towards
SF: Can only give you 40 if you are
a) Not under Lunar
b) Have <=35 eclipse energy

Wrath:
Gains of -26/-27, like SF, only happen when you are
a) Not under Solar
b) Have >=-35 eclipse energy

There is also nothing random about when -13 vs -14, especially since there can be no -26/27 towards the end. It is repeating pattern:
-13 -13 -14 -13 -13 -14 -13 -13 -14...
This would be awesome to have it show if the wrath that is in flight + the one you are casting at the moment are guaranteed to procs eclipse:
If you are at -74, one wrath flying, one casting => Your next cast should be Starfire
If you are at -73, one wrath flying, one casting and the last gain of wrath was -13 => You next cast should be Starfire
