4Game

The 4 armed champion.
He resides in the cursed colosseum. It is quite a big monument that was built by who knows what forgotten imperium.

Many heroes/looters that were brave or dumb enough to enter fell victim to the curse that makes one mind fill with hunger for battle. Even Axe was once here, killing hundreds of unlucky fellas. But he came to senses and left when he saw the champion, or better said the 4 legendary weapons that he has.

The guy is not much to talk about, just a powerful random warrior that was unlucky enough to be in the monument when the curse began.
But he is still alive after so many years, we could say he is kinda lucky that the legendary weapons that came in his posession protect him.

1.The first is the sword of giants, a crude piece of metal that can barely even be considered a weapon or sword . This weapon was allways at the side of the champion, even before the curse. This weapon can never be broken, is quite special. A trusty one to rely on, indeed.
First ability has 2 components, slash. Does ×2 the champion's damage and slows the enemies 50% for 2 seconds. The second part does ×1 the damage of the champion and stuns the enemy for 1/1.5/2/2.5 seconds.

1. The mace of vengeance. This is the king's weapon, the sad king of the forgotten imperium. Not much is known about it, but it packs a punch.
   This is a passive, the champion will retaliate after being atacked 8/6/4/2 times and lets him use his others abilities while he atacks or is cced. You clearly need to be in his range to get hit by this passive, if no one is it will be saved for when someone is.

2. The sickle of sun, this is quite powerful in the hands of a mage. It lets you use the sun or other sources of light to do defense or ofensive magic. It lets even this dumb piece of muscle to cast one spell.
   A fast aoe sunstrike comes from the sky to strike down on foes, it does around 200 pure/magic damage and stuns the enemy for 0.5/1/1.5/2.5 seconds the enemy. The range, idk.

3. The hammer of death and life. It can literally kill anyone, but our champion doesnt know that or doesnt know the way to do it. The champion can use it to revive or defend people because the hammer does it by it's free will. This weapon is the reason for which the curse began, a secret to be discovered another time.
   This is the ultimate, revive. You can revive yourself or an ally to full health and give them inviciblity for 1 second or if they are alive give them invicibility for 5 seconds. It is global and has 2 charges that are 200 secs in coowldown. You can also use it while you are dead of course, but the idea is it gets balanced by how you use it, risk and reward. If you revive yourself in the middle of 5 heroes of course you will just feed gold/xp.

Shard will give 2 charges of sunstrike.
One more charge of ultimate
Or a new a ability. I would not like to add more to him because i want to keep the idea that he is a cursed mindless warrior. Or that he escaped recently from the curse and doesnt know what he has in his hands.

Aghs
It adds a passive to him, when he falls under 25% hp he becomes enraged, just like ursa. Around 90% damage reduction and 90% status reduction. So you can still kill him, kinda.

He would be an offlaner or position 4. I think his passive would be a bit unbalanced against some heroes, but you are not forced to focus him and he gets countered by ranged heroes. You can kite him.
I just had this idea and wanted to put it here. I have more, but i know they will never make it into a game.
