Haunting Dreamscape is an event where you have to build teams with 
Awakened Ezizh and defeat teams that contain other awakened heroes. This event is available for players that have completed Campaign Stage 15-40.
After starting a new game, you will possess 6 six lives and you must defeat 8 different teams. Each enemy team will have a different awakened hero (
Thane, 
Belinda, 
Brutus, 
Solise, 
Baden, 
Talene, 
Athalia or 
Maetria). The game ends once you win the 8th battle or if you lose all lives.
But don’t worry if you lose all your lives, you can restart this game mode as many times as you want.
After each victory, Awakened Ezizh is automatically leveled up and you can choose to activate one of the two talent skills for him. The talent skills available depend on the enemy defeated.
Also, after each victory, you may enlist one of the four heroes provided by the system in your own formation. If the hero already exists in your formation, they can be ascended. Each hero can be ascended up to once at a maximum.
You will need to play this event multiple times to get enough achievement points to get all rewards.
Below you can see a tier list of talent skills, a tier list of allied heroes for this event and the complete mission list to get achievement points.
