Hades the King of the Underworld (ultimate build)

That's a nice guide. Though I completely agree with the order for skills (maybe I would get Shroud of Darkness lvl 1 before going for Devour Souls lvl 2, but that's OK), I have doubts regarding the item set, both mid and late game, at least for Conquest and Assault.

As Hades needs to be real close to his targets to deal damages and/or tank, I would have first bought the Hide of the Urchin. That's absolute priority if you want to be able to tank correctly. If you want to go full damage, your build is OK, but in that case you would probably prefer Scylla to Hades.
Also, the Book of Thoth is no longer a choice of mine. It's good for dealing damages, but it is not what is expected from Hades when you're playing 5vs5.
For Joust 3vs3, it can still be interesting, especially if all enemies are magical or all physical damage dealers (because you can probably remove 1 defensive item).

When I play 5vs5, I first go with Hide of the Urchin, but going with a starter item can be interesting. I'd rather choose Watcher's Gift than the Vampiric Shroud, but that's up to you.
Boots are not mandatory, but I know it's quite frustrating to be the slowest guy on the map, so you can probably afford to buy Boots, that you might improve or sell later.
Then I choose another defensive item according to which ennemy god(s) is(are) doing good in the game. Breastplate of Valor if the god is dealing physical damages, Spirit Robe if there is no clear leader or Bulwark of Hope if the god is dealing magical damages.
At this step, you should already have 3 defensive items. Then you can go for some damages. I prefer to start with Warlock's Sash in order to start stacking. Also you can go for Ethereal Staff for HP and MP because the passive is working better than the Rod of Tahuti at this step (it's the only MP item you have, so it just add up 125 * 1.25 = 31 MP) compared to the Ethereal Staff that probably already add 50 MP (2500 HP * 0.02).
As it can save your life to go average fast (in addition to Death From Below) for escape, you can choose it improve your Boots. Please note that if you use both Breastplate of Valor and Spirit Robe, you would be wise to choose the Shoes of the Magi, because you already have 40% CDR. I usually don't go for movement speed unless the game really requires to.
For the sixth item, I usally go for the Rod of Tahuti (if I have at least another MP item), Warlock's Sash or Ethereal Staff for damages. It is also possible to go with another defensive item if my team mates are already dealing a lot of damages and mostly need a tank.

Regarding actives, Shield of the Underworld is a must have before you throw Pillar of Agony. Shell of Absorption is also interesting. You can also go for an active that will improve your escape skills (either teleport or movement speed buff).

To sum-up, in most cases I would go this way :
Hide of the Urchin, Bulwark of Hope, Warlock's Sash, Breastplate of Valor, Spirit Robe, Ethereal Staff
Actives : Shield of the Underworld + Shell of Absorption or Greater Sprint

If you don't need/want to tank, there is another interesting item set :
Hide of the Urchin, Celestial Legion Helm, Void Stone, Warlock's Sash, Spirit Robe, Rod of Tahuti
Actives : Shield of the Underworld + Shell of Absorption or Greater Sprint

In both cases I do not use boots (I trust my defense!), but you can remove an item to put boots instead if you feel more confortable with boots.

Anyway, that's just my point of view! :)

I'll update it as soon as i have time, it was midnight when i made it XD

Nice build, gone try this out.
The guide could use some expanding, bit more about skills, possible combos. Maybe also add some situational items.
Also not the most beautiful guide out there, bit more work on coding.

Still looks like a good hades build, will vote up if it works in testing.
