Both extremely strong tames. They have a blink attack that once charged can jump between every target stunning them. As you attack they charge a special attack that once released is quite devastating. They're able to stealth. They can swim better than most sea creatures. They have a leap ability that can cover a lot of ground or help traverse vertically. And one of the coolest features is that they are a pack animal and recieve pack bonuses. The coolest feature is that when mate boosted the females gain the ability to stealth mostly everyone and thing within a close vicinity and the males have a roar that increases speed and recovers torpidity and stamina at an insane rate.
Both male and female can cloak themselves, but female can also cloak all dinos in an area around it, while the males cannot. The males can instead give a courage effect I imagine is similar to Yutys, but I don’t know for sure. Both male and female also have a powerful charged jump, and a dash attack where they teleport between a group of creatures and damage them, and also stun them for a couple seconds
So if you want the multitool of a pve, pvp monster dino here you go. Need to kill an alpha, Shadowmane, need a fast meat run use a shadowmane, need to kill a fast player shadowmane, kick a player off tame shadowmane, get drake eggs shadowmanes can jump, need to bait a creature with a fast tame shadowmane. Need a yuty for a boss, nah shadowmane, need a easy getaway dino shadowmane, need a boss army breed shadowmanes.
While tamed you must have a male and female present sharing the mate boost to allow the female to share the invisibility! I tried when I only had the female and it didn’t work!! Didn’t want anyone wondering why they only have a female and it won’t share the invis!! Hope this helps!
