Huge thanks to KyleTheScientist for helping me make the Blunderbeast Blight item and troubleshooting all the issues I had !

ALSO REQUIRES MY ITEM COLLECTION : 
https://modworkshop.net/mydownloads.php?action=view_down&did=25197

Important notes :

• To install character : Requires Mod the Gungeon. Extract "The Afflicted" folder from the first zip file and paste it in your CustomCharacterData folder after having booted up the game with Custom Characters Mod at least once.
  
• To make sure the items are installed properly, press F1 and check if the mod is enabled. If not, try deleting mods.txt and the relink cache folder then launch EtG again.
  
• The custom items will appear normally in the Gungeon when playing as other characters. 
  
• To spawn these items for other characters : open the MTG console with F2 or ~ and type in : give rtr:item_name
