I wish this site had a like option on posts. ^^ (Have a hypercondriac need to thank everyone)

I like this +1, always been a big fan of ninja's samurai etc. I watch a lot of Asian cinema. I have a question about the recipes you added, do they all make the effects you say, by combining any 3 of them ingredients? 

Take the "black eggs" recipe for instance, it has 10 ingredients, does a combination of any 3 give the desired effect.

Thank you very much for the like.  On your question.  What I did was list all the ingredients that can be used to produce those recipes.  Some ingredients are vital to the potion/poison, the others can be switched and swapped.  I didn't want to just give away the recipes because I believe this build really shines more on the RP front.  eg, JUNGLE FROG POISON:  (Paralysis/DMG Health/Lingering DMG Health).  The key element here is Human Flesh.  Without it, you will not be able to make the pot with all three elements.  Hope this helps :)

I'm nitpicking here, but would it not be better to list as say - ingredient 1, ingredient 2 + 1 of remainder of ingredients.That way people get the desired recipes without having to try different combinations to get desired effect.

For instance - Blue flower, butterfly wing + 1 of charred skeever, giants toe, blue dartwing etc. for elixir of emperor.

You make a valid point... something like a key ingredient list and what goes with it.  If enough people ask for it, i'll do it for sure, or maybe on my own when i have a break later.  Thank you for the suggestion.

In the end, for me the fun thing about alchemy is finding out what works with what.  Tasting, mixing, experimenting.  In this way my RP character doesn't build up too fast with one skill, and it feels like a natural progression.  I think I might have to put a disclaimer in front of the Recipe list to state that this is in this order for RP players, and then just link to the recipe calculator at the end for those who are too impatient. :)

Fabulous build, don't know why it doesn't have more likes. Makes a lot of sense in both worlds. Easy +1 from myself.

I would say something about Race.  i see you went Argonian, why?  Personally, Bosmer are the easiest for me to make look Asian, even Japanese, especially in the eyes which look out the mask.  Speaking of which, the outfit I've gotten closest to the "Ninja" look (In feudal Japan, the Shinjen didn't have a Uniform, they typically dressed as commoners, servants to infiltrate Shogunates, or Ronin to travel with a Sword.  At certain points, owning Weapons by any except the Bushi was illegal, and punishable by death, which is why the Ryukku weapons were adapted fro Farming impliments, or at least extremely concealable.) is the Shrouded Cowl, Nightingale/Boots/Gloves.  (The latter increase Sword damage, but not Daggers'.)

I like how you went Sword instead of Dagger, and non-magical/powers.  That's where this really differs from the vast majority of Stealth/Assassin builds, other than the thematic inspiration.
