Well, I met hedrack in level 4 of the temple. It was a tough and hard fight. I killed everyone except luz because he summoned into wall and he is unreachable.

I am able to explore furthure. And whenever I click on luz a dialog appear with a content similar of this: "why did you thought its neccessary to summon me hedrack?" and only available option are [continue].

My question is if I leave luz behinde and explore further doesnt it make the game to never end? If so I would load my progress again and fight with hedrack again.

Thank you.

I don't think this will be a problem. He doesn't play a role in anything else during the game.

Can you hit him with spells?

Can you cast Enlarge on him?

lol, funny.

After exploring to various places I came back to iuz, right clicked on him and choose coup de grace, now he is no longer into wall and I can fight with him.

This glitch can be useful to fight against hedrack :))
