I kinda would like to know which two-handed perks work with it and which one-handed I should get.

I would suggest Great Critical Charge for Two-Handed, but it almost never works.

You attack while sprinting and it's supposed to do extra critical damage, but I see no difference from normal power attacks.

Now if they were to patch this, I say go for it. You'll feel like a badass.

So should I just not get any two-handed perks at all?

Oh, you. You troll with innocense so well :3

In case you're srs, if you're going for the best Ebony Blade-wielding character you can get, go for all the perks that'll make you stronger. The perks that increase Two-Handed weapon damage and critical attack chances, make power attacks cost less stamina, beheading, sweep, etc.

And then there's Smithing, Enchanting, and Alchemy. Depending on how powerful you want to be and what difficulty setting you're going to play, of course.

Now play it like you didn't understand something I said. I love it when you annoy people with that x3

One handed perks work with the ebony blade. Not sure if this is glitched or a design choice. Although if you have the beheading perk for two handed it will work.
