Title says it all, shouldn't he have this and perhaps Darkness too?

This suggestion has already been made and we are working to update all of the dead and monstrous deities. For information specific to Ilbrandul and his domains, please read the following thread:

Should you be unable to create a character with these domains, please let a DM know in game or post a bug report.
