Was theorycrafting 500-point Death Guard lists and I found out to my dismay that at lower point levels, it gets difficult trying to squeeze everything in. The Plague Champion that's included in the First Strike boxed set for example, has a plasma gun and a power fist. It's quite a hefty loadout so I decided to swap its weapons out in the list. I had to magnetize the backpack and arms.
This gets even trickier in Kill Team, which is a smaller game.
I hope this helps someone:
