A quick update, and I apologise for the double post, but this is worth getting noticed. I got it to work! For once the man upstairs cut me some slack

Copy the Ability and Buff file of one of the other Gravity well abilities (Plasma Storm, Asteroid Field, etc...), then alter what you want in the buff file to your effects.
Then, well, I'll post a screen seeing as tab-spaces don't seem to work on this forum.

Its all there, I apologise for the blanks, they are secret at the moment, until 1.2 is released

You'll see the important bit, that gives the ability to the planet, which in turn seems to effect the Gravity Well and all things built by the planet, and possibly everything friendly in the grav well.
Hope that helps someone, 'cause its helped me a lot and could make for some interesting additions in Sins Plus. You heard it here first
