The game is not allowing me to fuse the four heroes to acquire Torturehelm. I have the four required heroes all leveled to 40 and fully ascended. Please fix the issue soon, as it is champion training event, and I would like to acquire and start leveling Torturehelm in order to receive the event points....

Issue has been resolved.

Hi

You need click one by one the champs and they added to fusion.
