Skills
His Skill-Set is amazing. Like already said, it opens many strategies you usually wouldn't have. His first skill Eternal Silence is pretty useful for Promotion Battle since it Silences the target and deals proper single-target damage. The third skills deal a tremendous amount of damage if they hit 4+ targets. Hades Knights second skill is Control of the Underworld even though it's a third skill (It got changed in an update). Thus Knight has 2 third skills.

Equipment Recommendation
Hades is a sole attacker so you should obviously build him as a damage dealer. When you have one with Breath of Death a little bit accuracy is needed as well. Always give him an Hp ring.

For Beginners (Without relics)

 * Dmg Build: You should have around 75% crit rate, doubled atk and hp and around 100% crit damage. Your Equipment could look like this:

2 times Strike-Set and 1 time Blade-Set with a crit rate necklace and an Hp ring.

Advanced Builds (With relics)

 * Dmg Build: Just like the Beginners Dmg Build, but with improved stats and other set-constellation. you should aim for 100% crit rate, 4k+ atk, at least doubled hp, at least 125% crit damage and a little bit accuracy. Your Equipment could look like this:

1 time Violent-Set and 2 times Blade-Set with an crit damage necklace (if too less crit rate take crit rate necklace) and an Hp ring. The subs should be focused on Atk, Crit Rate, Crit Damage, and Hp. The relics should have Defense Penetration +3% or Final Damage +5%.
