Lunar Surge, (Lane) (Ult) <- Does this deal too much damage? Please let me know :)

The 2x as much in night seems a bit OP. I don't know. But anyway, I think the duration on moonlit steps should be 10. However if you're going to do it like a conventional passive you could do 5/10/15/20.

Thanks, I changed the duration for the Moonlit Steps, I forgot to make it scale lol. So should I keep the 2x damage but reduce the amount it does or change it to something like 1.5x?

I would go 1.5 or something. Maybe a short silence or something too. I tend towards ults with multiple effects.

I added a short blindness, is it too long? Maybe 2.5 max or something.

This hero is extremely useful, but only at night, and even then it's still not so useful due to lack of damage (aside from her ulti), so I'm a bit sceptical about this idea.


EDIT:
Like kkoopman3 said, probably should add a silence to the 1st skill.

Yeah. 2 secs is a long time in DotA I suggest reducing the vision to... 200 or 300 so they at least know where attacks are coming from. Sorry if I'm imposing to much of my opinion on you. I can stop if you want.

I increased the amount of vision you have if blind. And I like hearing what other people say, so no problem.

I increased damage dealt with the first passive. But what do you suggest? Should I add another damaging ability that can be used in the day? It's quite difficult making a hero that is based around nighttime.

I like the nighttime theme. If you were to add an additional passive I think it would have to be just a conventional permanent 24 hour passive since the entire hero is based around the night.
