Dark Lord's corosive poison replacing Clarissa's poison damage but not vice versa

[mmetev]

As the thread title says - when i fire Clarissa first and then Dark Lord his corrosive poison replaces the Poison damage from Clarissa (although I believe they should stack at least with the mana generation reduction). But when I fire Clarissa after Dark Lord her poison damage does not replace Dark Lord’s corrosive poison.
I do believe that this is a bug and needs to be fixed.

Thanks for the information. As far as I understand corrosive is somewhe between dispellable and undispellable. For me this is a downside to certain extent.
