Warrior/Knight Help I Saw Something Amazing.

So some days ago I saw something amazing: a warrior was really fast because he could use the movement spell infinitely (somethimes he used the first spell in between) and I wondered... how is that possible (warriors spells cost a ton of mana) and he was really fast this way. I think he used Hero as weapon but I'm not sure. Could someone make an infinite charge-spell warrior-build because I can't.
It should be able to infinitely cast the charge-spell (with bash every two or 3 charge spells) and it should have some walk-speed :P
Have a nice day!

Sadly, he was probably using Idol, which has -charge cost with a max of -13 charge cost, allowing you to charge 15 times before spell cost starts rising.

Here's a build, the HP is really bad though https://wynndata.tk/s/qs6yj1

 

thanks bro

 

Idol actually used to have a -200% charge spell cost, which meant for infinite charging, TurboStratus made a video on this before it was nerfed in Hero Beta
