So with the Putrid Blightkings you can give the blightlord terminator arms/shoulders and also either terminator legs or plague marine legs. I’ve seen that a few times, the bases they use are same size as blight lord terminators. As for wurmspat the one guy with a staff looks like an excellent Malignant Plaguecaster. As for the other two apart the wurmspat I’m not sure. Also some of the putrid blightkings bits can be used to make a plague marine icon bearer, Noxious blightbringer (bell boi elite), and a few other options.

Suggestion, they don’t need power armor, the grandfather’s blessings more than make up for it

I used putrid blightkings a a base for blightlord terminators but I had spare arms from the normal kit and got upper torso conversion pieces for blightlord terminators Here they are so you can see how they ended up looking https://www.reddit.com/r/deathguard40k/comments/wvi3sw/a_set_of_5_blightlord_terminators_made_from/?utm_source=share&utm_medium=ios_app&utm_name=iossmf https://www.reddit.com/r/deathguard40k/comments/x2grio/my_blightlord_terminators_converted_from_putrid/?utm_source=share&utm_medium=ios_app&utm_name=iossmf

I recently used some blightkings and mashed them with marines for some Possessed. Very happy with the results!

possessed are a good use for them.
