Assassin/Ninja Help Inferno Build

Guys.
I might want an Inferno. How much should they go for? Is it still completely shit? Or is it even shittier now when it only deals pure fire damage and nothing else?
I also need a build for it. What I'd like is good damage, tankiness and some (like 5 or smthng) mana regen. Walk speed doesn't matter much, but Statue is still rejected.
The items I already have that I might want to use are Leo, Greaves of the Veneer and Scorpio. Is Third Eye somehow possible to fit in the build? Is antipode assassin as terrible as I think it is?
I know there are existing builds for Inferno, but they are outdated and meh. Of course I'd like to just use my own brain here, but I've never worked with the fire element before, therefore the results could be catastrophic.
Thanks to anyone that answers to any of these questions.

 

I guess for helmet you can use Fenmask (% spell and melee dmg buff, poison, % hp regen, a bit of mana regen, thorns and earth/water dmg, and the debuffs aren't too bad.) or even Snail Helmet (almost 4k max hp, raw and % hp regen, and a def buff, but this + Leo + Scorpio = -650 water def).
If you want you can use Hetusol instead of Leo for a bit less hp but no dmg debuffs, no -300 water def and some mana regen.

Im not good with builds btw and I dont know if Inferno is shit.

 

Why would inferno be bad because it deals only one element? Pure damage always does more than split damage, which makes inferno very good in terms damage capability. Additionally, many items in the game drastically increase fire damage, so pure fire damage is extremely strong except in few scenarios (qira, wybel. But those also resist thunder well, which is a major contender for high pure element damage)

Anyway, you definitely want to look into:

-vapor rings
-ardiente/capsaicin
-nether's scar

 

Thanks for the replies!
So basically I'll go all in with fire damage. Next thing are the skill points. 115 def is a must if I want to use the Inferno. Should my secondary element be thunder, water, earth or air? Air is probably bad, water could work because I won't be doing any other elemental damage anyways; its still good for mana capacity, some mana items and water defense. Thunder would give me a crit chance, but it has to be quite highly leveled to be worth it. Earth would give me access to things like Greaves of the Veneer and Scorpio, but then I will be super low on mana and mana regen.

What if I try to go for:
Shimmersight (I didn't find any other helm that would just give some Mana for free)
Hetusol (regen to counter Inferno's negative regen)
Ardiente (fire damage, better health than capsaicin)
Nether's Scar (just... good boots for this build I guess :D)
2x Vapor
Some kind of Bracelet
Royal Blazing Amulet
Raw skills: 100 def, enough dex ot make the crit chance 50%, rest in int

 

Does it not have any powder slots?

Also, I'd go for water as second element because I like spells, but earth might go better with it. Idk about thunder.

 

It does, but I think I'll use a Black for other damage types.
Thunder just seems to fit super well with the other items listed above.

 

Looking good, thanks for the reply! I'll take it in consideration.
