So the interface for making a prepared chant is baffling to me. How does this work? It seems I can endless add chants to the list. 

 

Any help is greatly appreciated. 

I think you can endlessly add them. The thing to watch is the durations. The dark green is the chanting, and the light green is the how long it lingers. I believe this is how you make them try and stack. I'm still not sure on the nuances yet.

Okay, so the basic idea is that you're defining pre-set modes for use in combat,  When you select a mode, your Chanter will use each phrase one after another in a loop.  So, a very basic set up is to have Mode A be a single phrase.  Your Chanter will use that phrase over and over until you select a different mode.  Alternatively, you could have Mode B alternate between two phrases by going Phrase 1, Phrase 2.  So you'll use the first phrase, then the second, then the first, then the second, and so-forth.  After X amount of phrases, you can use your invocation.  Honestly, I'm not sold on multiple phrases as a viable strategy, but I've only used one briefly, and he was a first level hire.

Thanks! Have to actually get some work done today, so I will take a stab at it later.
