I am looking at creating a TWF Warpriest for an upcoming campaign and was wondering how the action economy works if I am wielding two kukris but then want to swift cast using Fervor. Am I going to need to have Quick Draw in order to put one weapon away and then redraw it so I have an empty hand for, say, swift casting divine favor, or can I swift cast with both kukris in hand? It would just be a bummer to have to wait until 3rd level to have to pick up Quick Draw due to the 3/4 BAB.
Using fervor to cast with your hands full shouldn't be an issue:
Spells cast in this way [i.e. using the warpriest's fervor] ignore somatic components and do not provoke attacks of opportunity. The warpriest does not need to have a free hand to cast a spell in this way.
So dual-wield those kukris and use your powers for good or for awesome.
