Hades descends into the ground and erupts from below at his ground location, doing damage to all enemies in the area. If the enemy is Blighted, they are also Slowed. Applies Blight. Damage: 50/85/120/155/190 (+60% of your magical power) with a 20/25/30/35/40% slow for 2 seconds
Honestly 50-190 damage is a joke, so much of a joke kephri's 3rd ability deals more damage than it starting at 50 but scaling by 50 per level up to 250.
An increase of hades 1 (leap) from 190 to 250 (to have base damage just like kephri would be amazing.
Secondly, here is the tricky one. Detonate blight.
Hades devours the souls of his enemies, dealing damage in a radius around him. If the enemy is Blighted, the enemy explodes dealing damage to nearby enemies and healing your allies. Enemy gods only take 50% of the damage from detonating Blights. Consumes Blight.
*Damage: 75/115/155/195/235 (+70% of your magical power) Detonated *Damage: 20/27/34/41/48 (+50% of your magical power) *Detonated Healing: 25/35/45/55/65 (+15% of your magical power)
So this one is tricky, if hades has 550 magical power with his 3 at max level plus 9 minions around a god he can deal 2,000 damage with a SINGLE ability. This is insane until you realize this is just one super specific scenario.
If you blight someone and then use detonate blight the damage results in a pitifully low: 259 + (95% magical power)
So this ability quickly becomes an all or nothing that relies on Hades killing someone in the middle of 1 and 1/2 of a minion wave.
My suggestion: Hades devours the souls of his enemies, dealing damage in a radius around him. If the enemy is Blighted, the enemy explodes dealing damage to nearby enemies and healing your allies.
Enemy gods only take 50% of the damage from detonating Blights. Gods can only take damage from a maximum of 4 detonated blights at once. Consumes Blight.
So far this does two things. Firstly, it removes the edge cases of "What happened to my health?" of Hades chunking you because you stood within your own minion wave and it allows Hades 3 to have more room for a buff like so:
Increase the base damage of hades 3 from 75/115/155/195/235 (+70% of your magical power) to 80/135/190/245/300. While also lowering blighted damage to: 10/15/20/25/30 (+30% of magical power). <Numbers are not solid just something I plugged in for better examples.
What does all this mean:
It means hades 3 has the edge cases of just deleting a carry from 100-0 removed and allows his 3 to stand on its own as a solid damage ability without requiring excessive use of blighted minions but keeps the idea of Hades being specialized in minion wipe and teamfights. Simply, it is a power rebalance instead of an outright buff. This ALSO allows his 3 to clear a minion wave without having to use his 1 or 2 first. So hades can actively choose when he wants to use 145~185 mana to clear a wave, so he isn't healing every single time it shows up allowing him to make a decision of: "Do I want to heal? Or save my 2 to defend from potential ganks?"
Hades 3 is just a VERY outdated ability and a simple power rebalance to allow it to deal damage without blight would be extremely beneficial for the character.
TL;DR Buff the base damage of hades 1 and buff his 3's base damage, add a maximum blight damage cap to gods and lower blight damage total.
EDIT: With this change if he was too powerful you could even REMOVE the blight application from hades 1!
EDIT 2: This also makes balancing hades 3 easy because you have the variable of: "How many Explosions effect gods?" Rather than simply tuning up or down just a few damage numbers
