The females are the only ones that can cloak. Males give a buff to other shadowmanes. Also, males have bigger manes... or are they frills? What are the spikes on a lion fish called? Anyways, my advice is to use a male and a female, as they will boost each other, as well as mate boost.
Ive actually riden this, Wildcard let me do some testing. The melee is wayyy worse than you expect, its speed is bad, uts weight is actually really good, and it reduces the weight of anything in its inventory by 50%. Thats all I got for yall
