Unity of the Elements

I finished it. I really enjoyed both the story and the game as a whole. Please make more campaigns like this. I'm reporting issues encountered during the game. 1. I couldn't complete the quest to obtain the Titans. I collected all the artifacts, etc., and brought them to the shaman, but he said I had to wait. After that, the game froze. I had to skip this quest. 2. I didn't understand how to navigate the Path of the Abyss, so I had to proceed by trial and error, saving frequently. Please provide a more specific description, rather than just saying to follow the rainbow. I didn't notice any other errors, but I have a suggestion: fix the final boss; he's too easy to kill. If you create a wall of swords across the entire field, he can't break through it and just stands there doing nothing. All the hero has to do is slowly finish him off. Maybe give him (the final boss) the ability to summon elementals or use some other magic. It's your campaign, so it's up to you.
P.S. And I also couldn't collect the entire dragon artifact set; the necklace made of dragon teeth wasn't anywhere to be found, but I guess that was intentional.
