On another note, I have just run the Heartcoil Deeps Challenge four times.
Even with my best 4 x level 16 characters. each laden with levelled items, I was utterly unable to complete the challenge.
My progress went as follows:
1st Attempt - All four heroes killed in the fourth room.
2nd Attempt - All four heroes killed in the seventh room.
3rd Attempt - All four heroes killed in the seventh room.
Final attempt - All four heroes killed in the fifth room.
In each case my heroes were nearly fully health upon entering the room. However, the monsters in these rooms were much too powerful.
What makes this uber frustrating is that I just spent a month nagging the development team to correct my account because it was previously unplayable. They were reluctant to even look at it. Now after the update the dilemma has returned.
As I don’t want to nag Waldo and the Ludians for another month, I suppose I will need to use the hack and bump my players to level 25. This may be the only reasonable way to make it playable.
