Even if not interested by new shapes, I suggest v2 users to update since old shapes have been optimized
Note: v3 requires Flagrum 1.4.10 at least. The mod manager should already be self updated if recently used. Else open Flagrum for a couple minutes, then close it and open again (should display latest version)
Several alternative shapes for Frey's magic VFX, check picture for comparison with default and Burst Shot examples.
Applies to everything from Frey's spelltree, including Flow, Shimmy & Leap.
Note2: Sila's, Olas' & Prav's magic each have their own singular shape and I find them to fit their respective spells better. However I may add more versions if requested
