Can I ask if you like the tzeentch aesthetic at all?
For example, did you like the morphing 3rd ed metals and are now turned off by weird bracelet wearing squigs?
The Vrock by UltraForge is an excellent
LOC replacement as it looks less weedy
has less parts to assemble
has an excellent level of detail
This guy actually mis-posed his, the bottom of the staff is meant to pass between the wing and leg but you can see the level of detail that makes this thing a joy to paint.
