I have a flattened low-poly sphere. enter image description here

I need the vertices to be offset by a random amount along the Z-axis using the geometry nodes, but relative to their normal, ie not the global Z-axis, so that the shape looks like an asymmetric star. In other words, the displacement should go from the center in all directions to the outside, so that something like this comes out: enter image description here

Unfortunately, I can only move it along the global Z axis.. enter image description here

(Blender version: 3.6.0)

The only adjustment you need is to use some scale of the Normal to offset vertices, instead of Object-Z:

This version selects points around an icosphere to offset outwards:
