For generating scarification scars.
Tag explanation:

scarification - general purpose tag, not necessary for activation.

healed scar - an elevated(embossed) type of scar. Accompanying tag is pale scar.

fresh scar - trained on images of freshly carved scars, should give an engraving type scar, but is more likely to generate red elevated scars. Best used in negatives when generating healed scars. Using scarification tag alone works better to achieve this effect.

Thanks to moss image, you can prompt scar of whatever you like on wherever you like it.
