You may want to add that this build requires DLC's to function. 

P.S. I like the addition of Light Armour and Ritual Stone rather than Lord

So many people have access to the DLC that most builders don't bother to mention whether their build relies heavily on DLC content. 

Made the Perk spread and Equipment picture sizes bigger, they were a bit hard to read. Thanks, mate! 

Like Curse said, I thought the DLC were pretty common among players, but I added a DLC requirement nevertheless. The new changes felt better - well noticed by the way. 

You may want to utilize the Vampire Lord Glitch, using it's powers in human, or in this case mer, form, to always have Summon Gargoyle equipped, and when first entering combat, use it then switch it out with whatever you wish to. That way it's more like you're using the same powers as the angels, rather than as a last resort, use it all the time. Since the angels animate statues and sometimes bring them alive, much like what vampires in Skyrim do with Gargoyles.

What exactly does 1/5 sneak to assassins blade mean. At first I thought it was, put the first perk into sneak then use the route to assassins blade. But then you also added, sneak 1/5 to silence? Not sure if it means 2/5 sneak and everything else other than shadow warrior or not?

Only 1/5 stealth. Every other perk in the tree except for Shadow warrior. Was it not clear enough? I'll definitely change it if it causes confusion.

Looks good! 

I see you've improved this build quite a bit since the last time I looked at it. And I've even gotten around to watching Doctor Who. Needless to say the actual weeping angels are the creepiest things I've ever seen on television in a long while.
