I had never painted a power weapon before today.
It’s technically a zenophase blade from the Deathwatch, but it’s blue, so now it’s a regular old power…
…well, I deliberately modeled it about halfway between an axe and a sword, which are two weapon options in Heralds of Ruin.
The arm is a great one from the Tempestus Scions box, topped off with the zenophase blade.
