I really like this priest guy, especially the first concept, the chains look very interesting!
Just... this is a war. How much damage can a cook do? Maybe if he poisons the enemy with his bad cooking or something... I get the spice idea, maybe he even throws salt in the eyes of his enemies (and then they throw it back in the form of words) but you'll have to work really hard on such a concept, it could easily become way too silly.
