I was bad a while ago. I bought a bunch of stuff for my Lost and the Damned Epic army. This included a Tzeentch Firelord and three Tzeentch Doomwings. It also included most of a Nurgle Plague Tower. This was my fault: I did not research what a Plague Tower should look like, and it was missing the Plague Mortar up top and the Nurgle symbol staff on the back.
So, I improvised. I used a handcannon from the Privateer Press Devil Dogs mercenaries up top, and embedded it in a pustule of putty. I added some drips to make it seem bursting with pus. I then added putty to the back and three more pustules in the Nurgle symbol. I used a pin vise in the top pustule when it was cured, put in a small piece of paperclip, and covered it with putty to make a spurt of goo.
Yeah, it's not 100% authentic but it looks great and it's way cheaper.
Next: Ork shootas! The last of the shootas, then on to sluggas.
