I'm trying them in my first (solo) game with Marignon :
Naked they're useless, comma
The first I equipped had a poisoned dagger and a basic BS Plate : after killing some indies basic Commanders he was smashed by a paltry Barb leader
The current experimental one has Fire Bola and Fire Helmet, and a Skull Amulet (the one that creates skeletons) and fares much better. I'll give him a Shadow Robe I think, maybe a Barkskin Amulet also.
