So, I dont know, I m playing again afther some years, but in my mind there is no such memory about gar colossus begin invincible, I cant even chew trought the shield bar, I m using a temple guardian, and my memory toells me this hero didont have so much hard time dealing whit this T-mutant golem,
So, my question its easy, have the CP path make him more more more hard, its a bug who cheated him to become a god, Its me whit low level 20?
Anyway I trie to beat him up but never dealt dmg, even I try to edit my char, and stills cant damage him...
