This condition makes a lion's skin easily damaged and very easy to scar. Every rollover could add a scar to your lion's body or every time they Hunt or patrol could gain a a scar

They'd probably die after 4-5 years due to blood loss

I'd guess this could be Fertile, but with very risky.... risks to take if you really wanted to breed one.

Like one could like get very injured and probably even (albeit rarely) die due to it

Or maybe they'd not be as Fertile? ( Goddess fert goes down to high, Medium goes down to very low, low goes down to very low, very low stays the same )

Or maybe they could get more scars?

This Ig could be kinged...But I'd guess they'd only be able to breed to Goddess/very high/high fert lionesses and unless Goddess has a higher chance to fail, oh and every battle could add a scar too, also with lowered defense.

Does this all make sense??

Or maybe they could die at 2-3 years.

I was guessing this mut would be an adult lethal mut.
