The Lost Hemisphere blog has a review of the latest Hordes Warlock, Bethayne & Belphagor.
From their announcement:
Lost Hemisphere has posted a review of Bethayne and Belphagor, the latest warlock release for the Legion of Everblight for Privateer Press’ Hordes game.
This is the first model Privateer has released that’s intended to be modular on the battlefield, coming with magnets and interchangeable chest pieces for the warbeast Belphagor to represent the warlock Bethayne melding with her beast.
The review includes a brief video showing how the chest pieces are interchanged.
