If you get a Titan with elemental barrier, do not use heroes with the same element colour. Example here yellow. This means that if yellow puzzles get to hit the titan, the damage will go to the hero of the same element colour. So as if you try to cast status ailment to the titan, he will not get hurt but your hero will.
So scrape her out of this battle.
Replace with someone else of different elemental colour 😎
