Watching that video made me want to try this out and so far it's quite some fun. I'm trying this build out together with the Ranger/Chanter from the video. Some parts are quite self-explanatory, but there is one part I have difficulties to understand in chanter builds is the optimal setup of your chants. On a first glance I would assume you want to keep Brisk Recitation always active to increase the amount of phrases generated so you can spam more abilities. So I assume you just switch between the two chants in this build depending on if the situation calls for more skeleton support ?
I also assume you didn't pick Amplified Wave because the Damage/Focus is worse than that of Soul Shock and with the limited amount of resources you can't really spam it compared to an Ascendant ?
