It turns out that if you put phrases in your chants and then respec and don't pick those phrases again you can still use them ! As long as you don't remove them from your chant. So you make a chant with the all the phrases and then "sculpt" a custom chant from the original chant. This way I avoided picking any phrases at all.

Amazing - also that stuff like this still emerges after so many years after release.

So this is what it means to refrain from learning refrains.
