Retains its original name after taming. Can't be attacked unless activated by the quest Scout it Out. You either need to be on that quest, or get the help of someone who is, in order to interact with it. Once summoned you might have to fight your NPC assistants for aggro. Using a freezing trap may stop them attacking Irewing, and hunters have also been successful by landing on a tree that the NPCs can't reach.
Level scaling: In Shadowlands most NPCs will scale with the Hunter's level, within the constraints of their level range. Hunters can tame regular NPCs up to 2 levels higher than them, but can only tame elite NPCs of the hunter's level or below.
