Hades is an extremely powerful god in Smite 2. He is mainly focused on crowd control and AoE damage. It is an excellent choice for players who want gods with a lot of fight control. The passive (Blight) marks enemies that receive additional effects when they are hit by Hades abilities. Devour Souls consumes the brand passive, dealing area damage and healing Hades. Shroud of Darkness releases a wave of fear in front of you that silences and panics enemies with the passive mark. A Pillar of Agony, Hades pulls enemies around, dealing damage over time and applying his passive. Lastly, Death From Below causes Hades to move to a location, dealing area damage and applying his passive.
The ideal order in which skills evolve are: Devour Souls -> Pillar of Agony -> Shroud of Darkness -> Death From Below.
Regarding items, we should start with the Shoes of the Magi, which will give us some magical power and penetration. Essential items during the match are the Warlock Staff, which increases Hades life and magical power, increasing sustain, Breastplate of Valor, reducing his ability cooldown and increasing his physical defense, increasing Hades survivability and lastly the Ethereal Staff, increasing your health and offering a greater burst to Hades. During the game we can also choose for Void Stone or Gem of Isolation, the first one is excellent against magical damage and the second increasing Hades magical power even further, adding slowing effects. Lastly, we finish with the Rod of Tahuti, maximizing Hades damage.
During the game we must use Shroud of Darkness followed by Pillar of Agony to maximize group control. We can use Death From Below to start a fight or to escape a more complicated situation.
