Aparently i'm the one that hacks

We will still Look into this.


EDIT
After analyzing vid with @Gix ,we came to the conclusion that there were no hacks/cheats involved.

Have you thought about lag on your opponents side?

None of these spirits hit you.


And let me show you a similar thing which in this case is caused by the bone wall lag, while in your video case the lag it's mostly likely present at the opponent end.

Spirits indeed find their target automatically, besides you're both seeing eachother so can't be auto aim either.
Also notice how you are not taking dmg at all, by evading the spirits.
Thats why you see so many, because your opponent keeps casting in a possible delay scenario.

You, who has no lag at all, is recording this.
What happens, in any game, when you have no lag at all but the person next to you does have lag?
And moves, casts spells etc? You see him like sort of speedhacking, blinking out of nowhere, casting spells and yet only animation repeats itself or when his connecting resyncs with the server you may notice more casted spells like spirits in this case, right?

What makes the lag part credible is the damage.
You dont take as much dmg as you should have.
In fact you barely take any dmg at all.
There are quite some misses there

Can you notice how only the first 2-3 spirits actually hit you.
And the rest has no effect?
That's normally a lag scenario on your opponent end.
While in a cheating scenario you would have taken a whole lot more damage during the mentioned video timers but you can notice you're definetly not being hit by countless spirits as you see them on your screen which in that case you would have been long dead.

Why do you think you arent taking any dmg here?
To us it looked like your opponent desyncd for a fraction of a second.
Look closely, he's trying to cast spirits and you only see the animation, but nothing comes out.

But your opponent would have lost anyway.
You are very experienced as a pvp player.
But also too focused.
Perhaps that's why you couldn't distinguish the lag part on his side which is understandable as most people don't pay attention to that during pvp anyway.

And your opponent accused you of cheating because well... you indeed are quite good and it's a common practice to accuse skilled pvpers of cheating, just like in any other game.

Anyhow both duelers from this video will be kept under close observation and feel free to record yourselves during duel games, that's always a good thing to do.
