Styx Greek Goddess of Hatred, and the River Styx

Styx
Pantheon: Greek
Role: Healer, medic
Pros: High defense, ranged
Cons: Low attack

Passive: help From Bia
Styx calls for help from her children. So every 4th attack does extra damage and knocks them back.

Ability 1: River Blast
Styx blast a bit of water from her river in a straight line dealing damage to her enemies And slowing them down
Dmg: 80/90/120/150/190 Mana: 30/40/50/60/80

Ability 2:??? (I cant think of another ability.can any of you give me some ideas?)

Ability 3: Binding Oath
Styx chooses a frienly god to make an oath. The two gods/goddess now share any friendly buff until all buffs fade. Costs: 70/80/90/100/120/130

Ultimate: Dip into Styx
Styx creates a large circular body of water and giving allies in there are given invincibility but lowers defense afterwords. Enemies can damage them inside the river but not outside.
mana: 100/120/130/135 Lasts: 3/4/5/6/6.5

Ok I see a few problems with this. Her passive, how mush is the buff? For her 1 it does very little damage, and how much damage does the poisen do, or how much are they slowed? The 3 is it like if someone has a jungle buff that is shared? And for her ultimate, this only takes a single person out of combat, it literally does nothing else, no one is stupid enough to attack there own teammates. So mainly I just need some clarifying, the ideas are good though!

Passive: Braindead invisible power, something you should always avoid. If it doesn't change up your gameplay in any way, it's a bad and boring passive.

1: Solid, just needs a damage.

2: Copypasta of Ra's ability. Also, you realise that this ability only does 65 damage at max rank, right?

3: It's decent I suppose.

Ultimate: Good idea, but it's not going to work. I was hoping that this ability would have something to do with the river, but I guess not.

ok

Ultimate is ******edly overpowered. It basically means spam all your abilities beforehand (including the invincibility one), then go invincible AGAIN for 7.5 seconds (meaning the reduced defenses are pointless), while you spam basic attaks for 7.5 seconds.
That is, Get demonic grip, gem of binding, GG.

She brings nothing to the table interesting but a stupid amount of invulnerability, no CC at all, etc. She sounds like she has a slowing version of Ra's 1, an invicibility version of Hel's heal, a weird form of aphrodite's soul mate, and an aphrodite ult on steroids melded with artemis's speed steroid.

I don't see what her role is as she does nothing well except be impossible to kill through invulnerability.

Yeah that ult is is rtardedly overpower. At rank 1 it lasts longer than Aphrodite ult at rank 5. Her 2 is also WAY OVERPOWERED. Her passive is interesting, I like it better. The 3 I like. But honestly, put more thought into it before you change things.

Ok, change her ulti into Dip into River Styx. This is perfect ultimate ability. But to make it fair, make it so that enemies can only damage them from inside the river Styx, so there is some counterplay to it.

Her 1 still needs damage.

thanx ill change it

Also most of the Invincibility affects allies...

And is that supossed to be a good thing?
