VFX Recreation - Skyrim's 'Restoration' Spell
The Niagara system is made up of these four emitters

Only one 256x256 RGBA texture was used for the effect - a composite texture with 4 different kinds of noise baked into each texture channel

The materials for all the effects are a combination of panning these noise textures (often radially) and masking them with radial gradients
Here's the official version from Skyrim as reference!
