The rings are fairly straight-forward, just make them have some sort of Rotation and RotSpeed value (like -360, 90 or -75). Though the RotSpeed should be kept quite low.
The light rays going into the Ankh is quite easy as well. All it is is just a Size NumberSequence like this:
And if you want it more natural-looking, just make a NumberSequence for the Transparency value.
Rate, Lifetime, and the Rotation stuff are all fairly important as well, but I’ll let you experiment with those.
And keep in mind, all the particles are parented to an Attachment, so they won’t move around and stuff, even with LockedToPart disabled.
No I didn’t make the decals, the rings texture was from some kit and the light rays thing:
Sorry if this didn’t really help you, I’m bad at explaining things lol
