Carry on a Cat
Luna is an agility hard carry with a decent early game and good scaling through to the late game. Despite being fragile and somewhat vulnerable in all stages of the game, she has a strong nuke, a very good teamfight ultimate, the fastest base move speed in the game, very fast pushing, and is one of the best heroes in the game at farming stacked ancients.
Agility carry itemization tends to be fairly straightforward, but we'll go through all the items commonly built on Luna and why as well as covering what to level when and the reasoning behind it.
No, I don't know what her accent is either.
